Description

Technical Field

[0001] This application relates to the field of image processing technology, and particularly relates to an image processing method, a processing device, and a storage medium. Background Art

[0002] The existing High Efficiency Video Coding Standard Protocol (H.266 / VVC) proposes a video frame coding technology to improve the coding performance without significantly increasing the computational complexity.

[0003] In the process of conceiving and implementing this application, the inventors found that at least the following problems exist: During the encoding and decoding process, for example, in the prediction processing stage (such as intra-frame prediction or inter-frame prediction), the most likely list method may be used for prediction processing. However, when determining or obtaining the most likely list, the detailed features of the block, such as the sub-block features of the block, will be ignored, resulting in a lower accuracy rate of the most likely list for some blocks, and further leading to a worse processing effect.

These drawings and text descriptions are not intended to limit the scope of the concept of this application in any way, but to illustrate the concept of this application to those skilled in the art by referring to specific embodiments. Detailed Embodiments

[0094] Here, the exemplary embodiments will be described in detail, and the examples are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. On the contrary, they are merely examples of devices and methods consistent with some aspects of this application as detailed in the appended claims.

[0095] It should be noted that in this document, the terms "include", "including", or any other variants thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device that includes a series of elements not only includes those elements but also includes other elements not explicitly listed, or further includes elements inherent to such process, method, article, or device. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of additional identical elements in the process, method, article, or device that includes such element. In addition, components, features, and elements with the same name in different embodiments of this application may have the same meaning or different meanings, and their specific meanings need to be determined based on their explanations in the specific embodiments or further in combination with the context in the specific embodiments.

[0096] It should be understood that although the terms first, second, third, etc. may be used herein to describe various information, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this document, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein may be interpreted as "when" or "while" or "in response to determining". Furthermore, as used herein, the singular forms "a", "an", and "the" are also intended to include the plural forms unless the context indicates otherwise. It should be further understood that the terms "include", "including" indicate the presence of the stated features, steps, operations, elements, components, items, kinds, and / or groups, but do not exclude the presence, occurrence, or addition of one or more other features, steps, operations, elements, components, items, kinds, and / or groups. The terms "or", "and / or", "including at least one of the following" used in this application can be interpreted inclusively, or mean any one or any combination. For example, "including at least one of the following: A, B, C" means "any one of the following: A; B; C; A and B; A and C; B and C; A and B and C", and again, "A, B, or C" or "A, B, and / or C" means "any one of the following: A; B; C; A and B; A and C; B and C; A and B and C". An exception to this definition only occurs when the combination of elements, functions, steps, or operations is inherently mutually exclusive in some way.

[0097] It should be understood that although the steps in the flowchart in the embodiments of the present application are shown sequentially according to the arrows, these steps are not necessarily executed sequentially in the order indicated by the arrows. Unless there is a clear indication in this article, there is no strict order limit for the execution of these steps, and they can be executed in other orders. Moreover, at least a part of the steps in the figure may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same moment, but can be executed at different moments, and their execution order is not necessarily sequential, but can be executed alternately or in turn with at least a part of other steps or sub-steps or stages of other steps.

[0098] Depending on the context, the words "if" and "when" as used herein may be interpreted as "when" or "while" or "in response to determining" or "in response to detecting". Similarly, depending on the context, the phrase "if determined" or "if detected (stated condition or event)" may be interpreted as "when determined" or "in response to determining" or "when detected (stated condition or event)" or "in response to detecting (stated condition or event)".

[0099] It should be noted that in this article, step codes such as S10 and S20 are used. The purpose is to more clearly and briefly express the corresponding content and do not constitute a substantial limitation in terms of order. Those skilled in the art may execute S20 first and then S10 during specific implementation, etc., but these should all be within the protection scope of the present application.

[0100] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0101] In the following description, the suffixes such as "module", "component" or "unit" used to represent elements are only for the convenience of explaining the present application and have no specific meaning in themselves. Therefore, "module", "component" or "unit" can be used interchangeably.

The microphone 1042 can receive sounds (audio data) via the microphone 1042 in operating modes such as a phone call mode, a recording mode, a voice recognition mode, etc., and can process such sounds into audio data. The processed audio (voice) data can be output in a format that can be transmitted to a mobile communication base station via the radio frequency unit 101 in the case of the phone call mode. The microphone 1042 can implement various types of noise cancellation (or suppression) algorithms to cancel (or suppress) the noise or interference generated during the reception and transmission of audio signals.

[0110] The mobile terminal 100 further includes at least one sensor 105, such as a light sensor, a motion sensor, and other sensors.

Optionally, the user input unit 107 can include a touch panel 1071 and other input devices 1072. The touch panel 1071, also known as a touch screen, can collect touch operations of the user thereon or nearby (such as operations of the user using any suitable object or accessory such as a finger, a stylus, etc. on or near the touch panel 1071), and drive corresponding connection devices according to a preset program. The touch panel 1071 can include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the touch orientation of the user, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into contact coordinates, and then sends it to the processor 110, and can receive and execute the commands sent by the processor 110. In addition, the touch panel 1071 can be implemented in multiple types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 1071, the user input unit 107 can also include other input devices 1072. Optionally, the other input devices 1072 can include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, switch keys, etc.), a trackball, a mouse, a joystick, etc., and specific details are not limited here.

After the touch panel 1071 detects a touch operation thereon or nearby, it transmits the operation to the processor 110 to determine the type of touch event. Subsequently, the processor 110 provides a corresponding visual output on the display panel 1061 according to the type of touch event. Although in Figure 1 the touch panel 1071 and the display panel 1061 are implemented as two independent components to realize the input and output functions of the mobile terminal, in some embodiments, the touch panel 1071 and the display panel 1061 can be integrated to realize the input and output functions of the mobile terminal, and specific details are not limited here.

The interface unit 108 can be used to receive inputs from an external device (such as data information, power, etc.) and transmit the received inputs to one or more components within the mobile terminal 100 or can be used to transmit data between the mobile terminal 100 and the external device.

[0115] The memory 109 can be used to store software programs and various data. The memory 109 mainly includes a program storage area and a data storage area. Optionally, the program storage area can store an operating system, application programs required for at least one function (such as a sound playback function, an image playback function, etc.); the data storage area can store data created according to the use of the mobile phone (such as audio data, phone book, etc.). In addition, the memory 109 can include high-speed random access memory, and can also include non-volatile memory, such as at least one magnetic disk storage device, a flash memory device, or other volatile solid-state storage devices.

[0116] The processor 110 is the control center of the mobile terminal, connecting various parts of the entire mobile terminal through various interfaces and lines. By running or executing software programs and / or modules stored in the memory 109, and calling data stored in the memory 109, it executes various functions of the mobile terminal and processes data, thereby monitoring the mobile terminal as a whole. The processor 110 can include one or more processing units; preferably, the processor 110 can integrate an application processor and a modem processor. Optionally, the application processor mainly processes the operating system, user interface, and application programs, etc., and the modem processor mainly processes wireless communication. It can be understood that the above-mentioned modem processor may not be integrated into the processor 110.

[0117] The mobile terminal 100 can also include a power supply 111 (such as a battery) for powering each component. Preferably, the power supply 111 can be logically connected to the processor 110 through a power management system, so as to realize functions such as management of charging, discharging, and power consumption management through the power management system.

[0132] The first embodiment

[0133] Referring to Figure 5 , Figure 5 FIG. is a schematic flowchart of an image processing method shown according to the first embodiment. The image processing method of the embodiments of the present application can be applied to a processing device, including step S10: determining or obtaining a most likely mode list according to the sub-block features of the current block.

[0134] In this embodiment, the processing device can be a smart terminal, such as a mobile phone, a computer, etc., or a server, such as a local server or a cloud server. In this embodiment and the present application, the processing device is mainly exemplified by a smart terminal.

[0135] Optionally, the technical solution of this embodiment can be applied to fields such as image coding and decoding, video coding and decoding, hardware video coding and decoding, dedicated circuit video coding and decoding, real-time video coding and decoding, etc.

[0136] Optionally, for ease of understanding, a brief introduction to the coding and decoding architecture is first given: Referring to Figure 6, in the encoding and decoding framework, the input video frame can be segmented into blocks to obtain at least one block. Each block is subjected to frame transformation processing through a frame transformation module, and then the transformed video frame is input into modules such as transformation, quantization, intra-frame prediction, inter-frame coding, inverse quantization, inverse transformation, and loop filtering. The video frame processed by the quantization module is subjected to entropy coding to output bits such as 01011100. Motion estimation is performed based on the video frame obtained after loop filtering and the video frame after frame transformation processing to obtain motion information, and inter-frame prediction is performed based on the motion information.

[0137] Optionally, at the encoding end, the video frame is input into a frame processing module. After this module executes a certain selection rule, one or more operations among geometric transformation, downsampling, linear transformation, non-linear transformation, pre-filtering processing (in the case of filtering processing, there may be no mode information) are performed on the frame, and then the transformed frame is output. The transformed frame is input into subsequent modules such as transformation, quantization, intra-frame prediction, inter-frame coding, inverse quantization, and inverse transformation. The above processing results are input into a frame inverse transformation module, and after performing inverse geometric transformation, upsampling, filtering processing, etc., the decoded image is output. Optionally, loop filtering can be regarded as part of the frame inverse transformation module.

[0138] Optionally, at the decoding end, the bitstream is read, the transformation mode information (in the case of filtering, there may be no mode information) is parsed, inverse quantization, transformation, inter-frame prediction, intra-frame prediction, etc. are performed on the video stream, and the video frame (transformed at the encoding end) is decoded. After performing frame inverse transformation on the above video frame according to the mode information, the decoded image is output. Frame inverse transformation includes inverse geometric transformation, upsampling, filtering processing, etc. Optionally, loop filtering can be regarded as part of the frame inverse transformation module.

[0139] Optionally, during the encoding and decoding process, the most likely mode list may be used for processing in each link. For example, in the partitioning stage, the most likely mode list is used to obtain the partitioning mode to perform partitioning processing on the current block. In the prediction stage, the most likely mode list is used to obtain the prediction mode to perform prediction processing on the current block.

[0140] Optionally, for all blocks (such as image blocks), the most likely mode list is constructed in the same construction manner. For example, the most likely mode list is generated by sorting according to the selected mode (such as the prediction mode). However, due to the large number of features and differences between different blocks (such as image blocks), such as different sizes of sub-blocks within the block and different textures, etc., the accuracy of the most likely mode list on some blocks is low.

[0141] Optionally, the block in this embodiment can be an image block and can be at least one of the current block, neighbor block, non-neighbor block, co-located block, temporal block, cross-component block, default block, and candidate block.

[0142] Optionally, the current block may be an image block, and optionally, may be different blocks at different stages of encoding and decoding. For example, at the partitioning stage, it may be an image block to be partitioned, and at the prediction stage, it may be an image block to be predicted, etc.

[0143] Optionally, the current block may include at least one sub-block, and the features of at least one sub-block may be used as the sub-block features of the current block.

[0144] Optionally, the current block may include at least one sub-pixel region, and the features of at least one sub-pixel region may be used as the sub-block features of the current block.

[0145] Optionally, when the processing device is an encoding end, the current block may be processed according to the list of most likely modes determined or obtained based on the sub-block features of the current block.

[0146] Optionally, when the processing device is a decoding end, the current block may be processed according to the list of most likely modes determined or obtained based on the sub-block features of the current block.

[0147] Through the technical solution of this embodiment, it can be ensured that the list of most likely prediction modes is highly accurate for the sub-blocks of the current block. Further, when predicting and processing the current block through the most likely list, the processing effect can also be improved.

[0151] Optionally, the list of most likely modes of the current block may be determined or obtained according to the sub-block features of the current block;

[0152] Optionally, the list of most likely modes of at least one sub-block may be determined or obtained according to the sub-block features of the current block.

[0153] Optionally, the list of most likely modes of the current block may include at least one list of most likely sub-modes, and each list of most likely sub-modes corresponds to a sub-block. The list of most likely sub-modes may be used as the list of most likely modes of the sub-block.

[0154] Optionally, the list of most likely modes of the current block may also be processed based on the sub-block features to obtain K lists of most likely sub-modes. For example, for each sub-block, a candidate mode that matches the sub-block features of the sub-block is selected from the list of most likely modes of the current block, and the list of most likely sub-modes is generated based on the selected candidate mode. Optionally, K is a positive integer.

[0155] Optionally, the most likely pattern list of at least one sub-block can be determined or obtained based on the list of K most likely sub-patterns. For example, the list of the most likely sub-patterns can be directly used as the most likely pattern list of the sub-block, or the list of the most likely sub-patterns can be appropriately transformed (such as adjusting the positions of candidate patterns in the list of the most likely sub-patterns, etc.) to obtain the most likely pattern list of the sub-block.

[0156] Optionally, the most likely pattern list of the current block can also be determined or obtained based on the most likely pattern list of at least one sub-block. For example, the candidate patterns in the most likely pattern list of the current block can be determined or obtained according to the most likely pattern list of at least one sub-block.

[0157] Optionally, the sub-block features include at least one of the following methods 1 to 3.

[0160] Optionally, after determining the division rule for dividing the current block into sub-blocks, the encoding end can encode the division rule and transmit it to the decoding end in the form of a bitstream. The decoding end can obtain the division rule in the bitstream and directly use the division rule in the bitstream as the sub-block division rule to divide the current block to obtain at least one sub-block.

[0161] Optionally, the decoding end can obtain the syntax element in the bitstream, select the corresponding division rule from at least one division rule according to the syntax element as the sub-block division rule, and divide the current block according to the sub-block division rule to obtain at least one sub-block.

[0162] Optionally, at least one sub-block division rule can also be determined or obtained according to the features of the current block, and the current block can be divided according to the at least one sub-block division rule to obtain at least one sub-block.

[0163] Optionally, the features of the current block can be the same as or different from the sub-block features. The features of the current block can include the pixel values, size parameters, etc. of the current block.

[0164] Optionally, the sub-blocks obtained after dividing the current block can be non-rectangular or rectangular.

[0165] Optionally, the sub-block division rule can be used as the sub-block feature, and the most likely pattern list can be determined or obtained according to the sub-block division rule.

[0166] Through the technical solution of this embodiment, it is possible to use the sub-block partitioning rule determined or obtained according to at least one of the partitioning rules, syntax elements, and characteristics of the current block in the bitstream as a sub-block feature, and then determine or obtain the most likely mode list according to the sub-block feature. Furthermore, it can be ensured that the most likely mode list is closely related to the sub-block partitioning rule, and then a more appropriate most likely mode list can be determined or obtained. When the current block is processed according to the most likely mode list subsequently, the processing effect can also be improved.

Optionally, the position parameter of the sub-block and / or reference block can be determined or obtained according to the pixel coordinates of the sub-block and / or reference block.

[0170] Optionally, the size parameter may include at least one of the width, height, width-to-height ratio, block size, and block area of the sub-block and / or reference block, and may also include parameters related to the size parameter of the block, such as the width after format conversion.

[0171] Optionally, the content complexity may be the content filling degree of the sub-block and / or reference block, and may include the content change degree of the sub-block and / or reference block, such as the texture transformation degree, color change information, etc.

[0172] Optionally, the pixel type may be the pixel type of at least one pixel in the sub-block and / or reference block. The pixel type can be set in advance. For example, pixels greater than the preset pixel threshold are one type of pixel, and pixels less than the preset pixel threshold are another type of pixel.

[0173] Optionally, at least one of the shape parameter, position parameter, size parameter, content complexity, and pixel type of the sub-block and / or reference block can be used as a sub-block feature, and the most likely mode list can be determined or obtained according to the sub-block feature.

[0175] Through the technical solution of this embodiment, at least one of the shape parameter, position parameter, size parameter, content complexity, and pixel type of the sub-block and / or reference block can be used as a sub-block feature, and then the most likely mode list can be determined or obtained according to the sub-block feature. Furthermore, it can be ensured that the most likely mode list is closely related to at least one of the shape parameter, position parameter, size parameter, content complexity, and pixel type of the sub-block and / or reference block, and then a more appropriate most likely mode list can be determined or obtained. When the current block is processed according to the most likely mode list subsequently, the processing effect can also be improved.

[0178] Optionally, the reference template can be determined or obtained according to neighboring pixels (such as adjacent pixels) or pixels of other components. For example, a pixel region including neighboring pixels located above, to the left, and to the upper left of the current block and / or sub-block can be used as the reference template.

[0179] Optionally, the reference template can be a pixel region within the same component in the same frame (such as a reconstructed or predicted pixel region), or a pixel region within the same component in different frames.

[0230] Optionally, the pixel features of at least one of the reference template of the current block, neighbor blocks, non-neighbor blocks, co-located blocks, temporal blocks, cross-component blocks, default blocks, and candidate blocks can be used as the feature of the current block, or the pixel features of at least one item can be appropriately transformed (such as format conversion, numerical conversion, addition or subtraction operations, etc.) to obtain the feature of the current block.

[0231] Optionally, since the pixel features of a block can include the texture of the block, the degree of texture change, and pixel values, etc., the texture, the degree of texture change, and pixel values of at least one of the reference template of the current block, neighbor blocks, non-neighbor blocks, co-located blocks, temporal blocks, cross-component blocks, default blocks, and candidate blocks can be used as the feature of the current block.

Furthermore, it is possible to ensure that the most likely mode list is closely related to the pixel features of the block, and thus a more appropriate most likely mode list can be determined or obtained. When the current block is processed according to the most likely mode list subsequently, the processing effect can also be improved.

[0233] Method 6: The similarity between the reference template of the current block and at least one of the neighbor pixels, non-neighbor pixels, co-located block pixels, temporal block pixels, cross-component block pixels, default block pixels, and candidate block pixels;

[0234] Optionally, the neighbor pixels can be at least one pixel in the neighbor blocks.

[0235] Optionally, the non-neighbor pixels can be at least one pixel in the non-neighbor blocks.

[0236] Optionally, the co-location block pixel may be at least one pixel in the co-location block.

[0237] Optionally, the temporal block pixel may be at least one pixel in the temporal block.

[0238] Optionally, the cross-component block pixel may be at least one pixel in the cross-component block.

[0240] Optionally, the candidate block pixel may be at least one pixel in the candidate block.

[0241] Optionally, the reference template of the current block may be approximated as the pixels of the current block, and then the similarity between the reference template of the current block and at least one of the neighbor pixels, non-neighbor pixels, co-location block pixels, temporal block pixels, cross-component block pixels, default block pixels, and candidate block pixels is calculated.

[0242] Optionally, when calculating the similarity, a pre-set similarity function may be used for calculation. For example, the absolute difference between the reference template of the current block and the neighbor pixels is calculated, and the similarity between the reference template of the current block and the neighbor pixels is determined based on the absolute difference.

[0243] Optionally, when calculating the similarity, a neural network may be used for determination. For example, the reference template of the current block and the neighbor pixels, non-neighbor pixels, co-location block pixels, temporal block pixels, cross-component block pixels, default block pixels, and candidate block pixels are directly input into the neural network, and the similarities between the reference template of the current block and the neighbor pixels, non-neighbor pixels, co-location block pixels, temporal block pixels, cross-component block pixels, default block pixels, and candidate block pixels are output.

[0244] Optionally, the similarity between the reference template of the current block and at least one of the neighbor pixels, non-neighbor pixels, co-location block pixels, temporal block pixels, cross-component block pixels, default block pixels, and candidate block pixels may be used as the feature of the current block, or the similarity of at least one item may be appropriately transformed (such as format conversion, numerical conversion, addition or subtraction operations, etc.) to obtain the feature of the current block.

[0245] Through the technical solution of this embodiment, it is possible to determine or obtain the feature of the current block according to the similarity between the reference template of the current block and at least one of the neighboring pixels, non-neighboring pixels, co-located block pixels, temporal block pixels, cross-component block pixels, default block pixels, and candidate block pixels, and then determine or obtain the sub-block feature according to the feature of the current block, and further determine or obtain the most likely mode list according to the sub-block feature. Furthermore, it can be ensured that the most likely mode list is closely related to the similarity of the block, and then a more appropriate most likely mode list can be determined or obtained. When the current block is processed according to the most likely mode list subsequently, the processing effect can also be improved.

[0246] Way seven, the quantity of at least one of the neighboring block, non-neighboring block, co-located block, temporal block, cross-component block, default block, and candidate block;

[0247] Optionally, taking the neighboring block as an example for illustration, the quantity of the neighboring blocks of the current block can be determined. For example, scan the neighboring blocks in a certain order and determine the quantity of the scanned neighboring blocks. For example, take the image blocks with a pixel distance less than the preset pixel distance from the current block as neighboring blocks and determine the quantity of the selected neighboring blocks. For example, take the image blocks within a certain range as neighboring blocks and determine the quantity of the selected neighboring blocks.

[0248] Optionally, it can be determined that the quantity of at least one of the neighboring block, non-neighboring block, co-located block, temporal block, cross-component block, default block, and candidate block is the feature of the current block. It is also possible to appropriately transform the quantity of at least one item (such as performing format conversion, numerical conversion, addition or subtraction operations, etc.) to obtain the feature of the current block.

[0249] Through the technical solution of this embodiment, it is possible to determine or obtain the feature of the current block according to the quantity of at least one of the neighboring block, non-neighboring block, co-located block, temporal block, cross-component block, default block, and candidate block, and then determine or obtain the sub-block feature according to the feature of the current block, and further determine or obtain the most likely mode list according to the sub-block feature. Furthermore, it can be ensured that the most likely mode list is closely related to the quantity of the block, and then a more appropriate most likely mode list can be determined or obtained. When the current block is processed according to the most likely mode list subsequently, the processing effect can also be improved.

[0250] Way eight, the mode of at least one of the neighboring block, non-neighboring block, co-located block, temporal block, cross-component block, default block, and candidate block.

[0251] Optionally, the mode may include at least one of the intra prediction mode, inter prediction mode, intra block vector mode, inter block vector mode, inter-frame partitioning method, cross-component prediction mode, geometric partitioning mode, spatial geometric partitioning mode, and block partitioning method.

[0252] Optionally, for different stages in the video encoding and decoding process, the mode adopted by at least one of the neighbor blocks, non-neighbor blocks, co-located blocks, temporal blocks, cross-component blocks, default blocks, and candidate blocks can be used as the feature of the current block.

[0253] For example, in the inter prediction stage, at least one of the inter prediction modes used by neighbor blocks, non-neighbor blocks, co-located blocks, temporal blocks, cross-component blocks, default blocks, and candidate blocks can be used as the feature of the current block.

[0254] Optionally, the mode of at least one of the neighbor blocks, non-neighbor blocks, co-located blocks, temporal blocks, cross-component blocks, default blocks, and candidate blocks can be used as the feature of the current block, or the mode of at least one can be appropriately deformed to obtain the feature of the current block.

[0255] Through the technical solution of this embodiment, it is possible to determine or obtain the feature of the current block according to the mode of at least one of the neighbor blocks, non-neighbor blocks, co-located blocks, temporal blocks, cross-component blocks, default blocks, and candidate blocks, then determine or obtain the sub-block feature according to the feature of the current block, and further determine or obtain the most likely mode list according to the sub-block feature. Furthermore, it can ensure that the most likely mode list is closely related to the mode of the block, and then a more appropriate most likely mode list can be determined or obtained, so that when the current block is processed according to the most likely mode list subsequently, the processing effect can also be improved.

[0256] Fourth Embodiment

[0257] Based on any of the above embodiments, a fourth embodiment is proposed.

[0258] In this embodiment, referring to Figure 13 , step S10 includes step S101 and step S102:

[0259] Step S101, determine or obtain at least one list construction rule according to the sub-block feature of the current block, and / or the execution order corresponding to at least one list construction rule;

[0260] Optionally, if the sub-block features of the current block are different, the corresponding list construction rules can be different.

[0261] Optionally, if the sub-block features of the current block are different, the execution orders of the corresponding list construction rules can be different.

[0262] Optionally, the correspondence between sub-block features and at least one list construction rule can be established in advance. After obtaining the actual sub-block features, at least one list construction rule can be determined or obtained according to the correspondence, and then the most likely pattern list can be constructed according to the at least one list construction rule to determine or obtain the most likely pattern list.

[0263] Optionally, different sub-block features may correspond to different list construction rules. For example, when the features of the current block include Feature 1, the list construction rule may include List Construction Rule 1, or when the features of the current block include Feature 2, the list construction rule may include List Construction Rule 2.

[0264] Optionally, different features of the current block may correspond to different numbers of list construction rules.

[0265] Optionally, the types of the corresponding list construction rules are different.

[0266] Optionally, the content of the corresponding list construction rules is different, and / or the execution order of the corresponding list construction rules is different.

[0267] For example, if the current block and / or sub-block is a smooth area (such as the sky, background), the dependence on the Planar mode can be reduced, and the DIMD (Decoder-side Intra Mode Derivation) mode or other modes suitable for smooth areas can be given priority. If there are areas with complex textures (such as edges, texture-dense areas) in the current block and / or sub-block, the weights of more non-adjacent blocks (such as non-neighbor blocks) or DIMD Blend Modes can be increased. That is, different textures of the current block and / or sub-block correspond to different list construction rules.

[0268] Optionally, the weights of DIMD Blend Modes can be dynamically adjusted according to the mode distribution and texture features of blocks such as neighbor blocks and non-neighbor blocks to make it more conform to the dynamic characteristics of sub-blocks in the current block.

[0269] Optionally, the length of the most likely pattern list can be dynamically adjusted according to the size of the current block and / or sub-block. For example, larger blocks use more patterns, and smaller blocks use fewer patterns.

[0270] Optionally, the number of candidate patterns can be dynamically adjusted according to the complexity of the block content of the current block and / or sub-block. More candidate patterns are used in complex areas, and fewer candidate patterns are used in simple areas.

[0271] Optionally, the content of the default mode can be dynamically adjusted according to the block mode or adjacent block mode of the current block and / or sub-block.

[0272] Optionally, a new default mode may be generated by combining the neighboring block mode and the DIMD mode to adapt to different video contents and scenes.

[0273] Step S102: determining or obtaining a most probable pattern list according to at least one list construction rule and / or an execution order corresponding to at least one list construction rule.

[0274] Optionally, after determining at least one list construction rule, a most probable pattern list including at least one candidate pattern may be constructed according to the at least one list construction rule and at least one candidate pattern.

[0275] Optionally, the candidate mode can be determined or obtained based on at least one of the neighbor blocks, non-neighbor blocks, co-located blocks, time domain blocks, cross-component blocks, default blocks and candidate blocks corresponding to the current block or sub-block, such as directly taking the mode of the neighbor block as the candidate mode. Optionally, different modes may correspond to different encoding and decoding stages, such as intra-frame prediction mode, inter-frame prediction mode, intra-frame block vector mode, inter-frame block vector mode, inter-frame partitioning method, cross-component prediction mode, geometric partitioning mode, spatial geometric partitioning mode and / or block partitioning method, etc.

[0276] Optionally, after determining at least one list construction rule and the execution order corresponding to the at least one list construction rule, the at least one list construction rule may be executed in sequence according to the execution order to construct the most probable pattern list.

[0277] Alternatively, if Figure 14 As shown, if the sub-blocks of the current block and its neighboring blocks are known, the current block and / or sub-block information, and / or neighboring block information can be input into a feature extraction module for feature extraction to obtain sub-block features. Optionally, the current block and / or sub-block information, and / or neighboring block information can include pixels of neighboring blocks, etc.

[0278] Optionally, Figure 14 The selector module in can select the switch to different list construction rules (such as list construction 1, list construction i and list construction n, etc.) according to the characteristics of the current block, so as to construct the most likely pattern list according to different list construction rules.

[0279] Through the technical solution of this embodiment, it is possible to determine or obtain the list construction rules and / or the execution order of the list construction rules corresponding to the most likely pattern list according to the sub-block characteristics of the current block, thereby reflecting that the most likely pattern has comprehensive consideration of the sub-block characteristics, and thus the most likely pattern list determined or obtained according to the list construction rules and / or the execution order of the list construction rules can be more accurate, and when the current block is subsequently processed according to the most likely pattern list, the processing effect can also be improved.

[0280] Fifth embodiment

[0281] Based on any of the above embodiments, a fifth embodiment is proposed.

[0282] In this embodiment, step S101 includes at least one of the following methods nine to fourteen:

[0283] Method nine: If the sub-block feature satisfies the first condition, determine at least one list construction rule as the first list construction rule;

[0284] Optionally, the first condition can be a pre-set condition. Optionally, the first condition can be set based on any feature of the current block.

[0285] Optionally, when constructing the most likely pattern list, the sub-block feature can be detected, and when it is determined that the sub-block feature satisfies the first condition, at least one list construction rule is selected from the pre-set at least one list construction rule as the first list construction rule, and the most likely pattern list is constructed according to the first list construction rule.

[0286] Optionally, for the same type of list construction rules, at least one list construction rule can be selected as the first list construction rule according to the sub-block feature, and the most likely pattern list is determined or obtained according to the first list construction rule.

[0287] Through the technical solution of this embodiment, it is possible to realize that the method for determining or obtaining the most likely pattern list is closely related to the sub-block feature, and when the sub-block feature satisfies the first condition, at least one list construction rule is determined as the first list construction rule, which can improve the accuracy of the most likely pattern list determined or obtained according to the first list construction rule in the current block, that is, a more suitable most likely pattern list can be generated.

[0288] Method ten: If the sub-block feature does not satisfy the first condition, determine at least one list construction rule as the second list construction rule;

[0289] Optionally, when constructing the most likely pattern list, the sub-block feature can be detected, and when it is determined that the sub-block feature does not satisfy the first condition, at least one list construction rule can be selected from the at least one list construction rule extracted and set as the second list construction rule, and the most likely pattern list is constructed according to the second list construction rule.

[0290] Optionally, for the same type of at least one list construction rule, at least one list construction rule can be selected according to the sub-block feature for constructing the most likely pattern list.

[0291] Optionally, if there is at least one list construction rule of the same type and the sub-block feature satisfies the first condition, at least one list construction rule can be selected from the list construction rules of the same type as the first list construction rule, and the most likely pattern list can be constructed according to the first list construction rule; and / or, if the sub-block feature does not satisfy the first condition, at least one list construction rule can be selected from the list construction rules of the same type as the second list construction rule, and the most likely pattern list can be constructed according to the second list construction rule.

[0292] Optionally, there can be at least one type of list construction rule.

[0293] Through the technical solution of this embodiment, it is possible to make the determination or acquisition method of the most likely pattern list closely related to the sub-block feature. When the sub-block feature does not satisfy the first condition, determining at least one list construction rule as the second list construction rule can improve the accuracy of the most likely pattern list determined or obtained according to the second list construction rule in the current block, that is, a more suitable most likely pattern list can be generated.

[0294] Method Eleven: If the list construction rule includes both the first list construction rule and the second list construction rule and the sub-block feature satisfies the second condition, the execution order of the first list construction rule is greater than that of the second list construction rule;

[0295] Optionally, the first condition and the second condition can be the same or different.

[0296] Optionally, if some sub-block features of the current block satisfy the first condition and some other sub-block features do not satisfy the first condition, it can be determined that the list construction rule for constructing the most likely pattern list includes both the first list construction rule and the second list construction rule.

[0297] Optionally, some sub-block features and some other sub-block features can be determined according to at least one of Method One and Method Three, and the some sub-block features and the some other sub-block features are different from each other.

[0298] Optionally, if the list construction rule corresponding to the most likely pattern list determined according to the sub-block feature includes the first list construction rule and the second list construction rule, at least one sub-block feature can be further judged. If there is at least one sub-block feature that satisfies the second condition, it can be determined that the execution order of the first list construction rule is greater than that of the second list construction rule.

[0299] Optionally, for the current block, if it has been determined that the list construction rules include a first list construction rule and a second list construction rule, the detection of at least one sub-block feature of the current block can be continued. If there is a sub-block feature that meets the second condition, when constructing the most likely pattern list, the first list construction rule can be preferentially executed, and then the second list construction rule can be executed until the most likely pattern list is determined or obtained.

[0300] Through the technical solution of this embodiment, it is possible to make the determination or obtaining method of the most likely pattern list closely related to the sub-block features. When the list construction rules include a first list construction rule and a second list construction rule, and the sub-block features meet the second condition, it is determined that the execution order of the first list construction rule is higher than that of the second list construction rule. Furthermore, the first list construction rule and the second list construction rule can be executed in sequence according to the execution order to determine or obtain the most likely pattern list. Further, since the most likely pattern list comprehensively considers the detailed features of the block, that is, the sub-block features, the processing effect can also be improved when the most likely pattern list is subsequently applied to process the current block.

[0301] Method 12: If the list construction rules include both a first list construction rule and a second list construction rule, and the sub-block features do not meet the second condition, the execution order of the first list construction rule is lower than that of the second list construction rule;

[0302] Optionally, for the current block, if there are some sub-block features that meet the first condition and there are other sub-block features that do not meet the first condition. For example, the sub-block features determined according to Method 1 meet the first condition, and the sub-block features determined according to Method 2 do not meet the first condition, it can be determined that the list construction rules include both a first list construction rule and a second list construction rule.

[0303] Optionally, at least one sub-block feature of the current block can be judged. If all sub-block features do not meet the second condition, it can be determined that the execution order of the first list construction rule is lower than that of the second list construction rule;

[0304] Optionally, at least one sub-block feature can be selected from all sub-block features of the current block. If the at least one selected sub-block feature meets the second condition, it can be determined that the execution order of the first list construction rule is higher than that of the second list construction rule; and / or, if the at least one selected sub-block feature does not meet the second condition, it can be determined that the execution order of the first list construction rule is lower than that of the second list construction rule.

[0305] Through the technical solution of this embodiment, it is possible to make the determination or acquisition method of the most likely pattern list closely related to the sub-block features. When the list construction rules include the first list construction rule and the second list construction rule, and the sub-block features do not meet the second condition, it is determined that the execution order of the first list construction rule is less than that of the second list construction rule. Furthermore, the second list construction rule and the first list construction rule can be executed in sequence according to the execution order to determine or obtain the most likely pattern list. Further, since the most likely pattern list comprehensively considers the detailed features of the block, that is, the sub-block features, the processing effect can also be improved when the most likely pattern list is subsequently applied to process the current block.

[0306] Way 13: If the list construction rules only include the first list construction rule, then determine that the execution order of the first list construction rule corresponding to the sub-block features that meet the third condition is greater than the execution order of the first list construction rule corresponding to the sub-block features that meet the fourth condition.

[0307] Optionally, the third condition can be the same as or different from the first condition or the second condition, and the fourth condition can be the same as or different from the first condition or the second condition. Optionally, the third condition and the fourth condition are different from each other.

[0308] Optionally, if the sub-block features of the current block meet the first condition and there are no sub-block features that do not meet the first condition, then it can be determined that the list construction rules only include the first list construction rule; or, if it is only necessary to detect at least one selected sub-block feature in the current block and it is detected that at least one selected sub-block feature meets the first condition, then it can be determined that the list construction rules only include the first list construction rule.

[0309] Optionally, the corresponding relationship between each list construction rule and at least one sub-block feature can be set in advance. That is, each list construction rule corresponds to at least one sub-block feature.

[0310] Optionally, if there is at least one first list construction rule, then the sub-block features corresponding to each first list construction rule can be determined.

[0311] Optionally, if there are sub-block features corresponding to the first list construction rule that meet the third condition and there are sub-block features corresponding to the first list construction rule that meet the fourth condition, then it can be determined that the execution order of the first list construction rule corresponding to the sub-block features that meet the third condition is greater than the execution order of the first list construction rule corresponding to the sub-block features that meet the fourth condition.

[0312] Optionally, if the fourth condition includes not meeting the third condition, that is, if the sub-block features corresponding to the first list construction rule do not meet the third condition, then it can be determined that the sub-block features corresponding to the first list construction rule meet the fourth condition.

[0313] Optionally, if the third condition includes not satisfying the fourth condition, that is, if the sub-block feature corresponding to the first list construction rule does not satisfy the fourth condition, it can be determined that the sub-block feature corresponding to the first list construction rule satisfies the third condition.

[0314] Optionally, the third condition and the fourth condition can also be independent of each other, and the priority of the first list construction rule corresponding to the sub-block feature that satisfies the third condition is higher than the priority of the first list construction rule corresponding to the sub-block feature that satisfies the fourth condition.

[0315] Through the technical solution of this embodiment, it is possible to realize that the determination or obtaining method of the most likely pattern list is closely related to the sub-block feature. When the list construction rule only includes the first list construction rule, the first list construction rule corresponding to the sub-block feature that satisfies the third condition will be preferentially executed, and then the first list construction rule corresponding to the sub-block feature that satisfies the fourth condition will be executed to determine or obtain the most likely pattern list. Further, since the most likely pattern list comprehensively considers the detailed features of the block, that is, the sub-block feature, the processing effect can also be improved when the most likely pattern list is subsequently used to process the current block.

[0316] Method 14: If the list construction rule only includes the second list construction rule, determine that the execution order of the second list construction rule corresponding to the sub-block feature that satisfies the fifth condition is greater than the execution order of the second list construction rule corresponding to the sub-block feature that satisfies the sixth condition.

[0317] Optionally, the fifth condition can be the same as or different from any one of the first to fourth conditions, the sixth condition can be the same as or different from any one of the first to fourth conditions, and the fifth condition and the sixth condition are different from each other.

[0318] Optionally, if the sub-block feature of the current block does not satisfy the first condition and there is no sub-block feature that satisfies the first condition, it can be determined that the list construction rule only includes the second list construction rule; or, if it is only necessary to detect at least one selected sub-block feature in the current block and it is detected that the selected sub-block feature does not satisfy the first condition, it can be determined that the list construction rule only includes the second list construction rule.

[0319] Optionally, the corresponding relationship between each list construction rule and at least one sub-block feature can be set in advance, that is, each list construction rule corresponds to at least one sub-block feature.

[0320] Optionally, if there is at least one second list construction rule, the sub-block feature corresponding to each second list construction rule can be determined.

[0321] Optionally, if there are sub-block features corresponding to the second list construction rule that satisfy the fifth condition and there are sub-block features corresponding to the second list construction rule that satisfy the sixth condition, then the execution order of the second list construction rule corresponding to the sub-block features that satisfy the fifth condition can be determined to be greater than the execution order of the second list construction rule corresponding to the sub-block features that satisfy the sixth condition.

[0322] Optionally, if the sixth condition includes not satisfying the fifth condition, that is, if the sub-block features corresponding to the second list construction rule do not satisfy the fifth condition, then it can be determined that the sub-block features corresponding to the second list construction rule satisfy the sixth condition.

[0323] Optionally, if the fifth condition includes not satisfying the sixth condition, that is, if the sub-block features corresponding to the second list construction rule do not satisfy the sixth condition, then it can be determined that the sub-block features corresponding to the second list construction rule satisfy the fifth condition.

[0324] Optionally, the fifth condition and the sixth condition can also be independent of each other, and the priority of the second list construction rule corresponding to the sub-block features that satisfy the fifth condition is higher than the priority of the second list construction rule corresponding to the sub-block features that satisfy the sixth condition.

[0325] Through the technical solution of this embodiment, it is possible to realize that the determination or obtaining method of the most likely pattern list is closely related to the sub-block features. When the list construction rule only includes the second list construction rule, the second list construction rule corresponding to the sub-block features that satisfy the fifth condition will be preferentially executed, and then the second list construction rule corresponding to the sub-block features that satisfy the sixth condition will be executed to determine or obtain the most likely pattern list. Further, since the most likely pattern list comprehensively considers the detailed features of the block, that is, the sub-block features, the processing effect can also be improved when the most likely pattern list is subsequently applied to process the current block.

[0326] Sixth Embodiment

[0327] Based on any of the above embodiments, the sixth embodiment is proposed.

[0328] In this embodiment, the first condition, the second condition, the third condition, the fourth condition, the fifth condition, and / or the sixth condition are determined or obtained according to at least one of the following methods fifteen to twenty-five:

[0329] Method fifteen, the matching result between the sub-block division rule and the preset division rule or the preset division rule range;

[0330] Optionally, the preset division rule can be a rule for sub-block division of the current block set in advance, such as dividing along the diagonal, dividing according to a certain reference line, etc.

[0331] Optionally, the preset division rule range can include at least one division rule.

[0332] Optionally, the matching result includes a sub-block division rule, and whether it matches or does not match a preset division rule or a preset division rule range.

[0333] Optionally, if the sub-block division rule includes a preset division rule, it can be determined that the sub-block division rule matches the preset division rule; or, if the sub-block division rule is within the preset division rule range, it can be determined that the sub-block division rule matches the preset division rule range; or, if the sub-block division rule does not include the preset division rule, that is, the sub-block division rule is different from the preset division rule, it can be determined that the sub-block division rule does not match the preset division rule; or, if any division rule existing within the preset division rule range is different from the sub-block division rule, that is, the sub-block division rule is not within the preset division rule range, it can be determined that the sub-block division rule does not match the preset division rule range.

[0334] Optionally, if the sub-block division rule matches the preset division rule or the preset division range, it can be determined that the sub-block feature satisfies at least one of the first condition, the second condition, the third condition, the fourth condition, the fifth condition, and the sixth condition.

[0335] Optionally, if the sub-block division rule does not match the preset division rule or the preset division range, it can be determined that the sub-block feature satisfies at least one of the first condition, the second condition, the third condition, the fourth condition, the fifth condition, and the sixth condition.

[0336] The technical solution of this embodiment can determine or obtain the first condition, the second condition, the third condition, the fourth condition, the fifth condition, and / or the sixth condition according to the matching result of the sub-block division rule and the preset division rule or the preset division rule range, and further determine or obtain the list construction rule and the execution order of the list construction rule, so that the most likely pattern list determined or obtained according to the list construction rule and the execution order of the list construction rule is more accurate. Further, since the most likely pattern list comprehensively considers the detailed features of the block, that is, the sub-block features, the processing effect can also be improved when the most likely pattern list is subsequently applied to process the current block.

[0535] Optionally, if it is necessary to construct the most likely mode list for the current block, an appropriate list construction rule can be selected according to the sub-block features. For example, when the sub-block features do not meet the first condition, it can be determined that the second list construction rule includes determining or obtaining the position of at least one candidate mode in the most likely mode list according to the calculation result of calculating the cost of at least one candidate mode according to the second cost function, and then constructing the most likely mode list according to the second list construction rule.

[0536] Optionally, if some of the sub-block features of the current block satisfy the first condition and some do not, at least one of the methods from method twenty-six to method thirty-five can be used to determine or obtain the first list construction rule. When the first list construction rule includes method twenty-six, at least one of the methods from method thirty-seven to method thirty-eight can be used to determine or obtain the second list construction rule; or, when the first list construction rule includes method twenty-seven, at least one of method thirty-six and method thirty-eight can be used to determine or obtain the second list construction rule; or, when the first list construction rule includes method twenty-eight, at least one of the methods from method thirty-six to method thirty-seven can be used to determine or obtain the second list construction rule.

[0537] Optionally, the most likely pattern list can be determined or obtained based on the first list construction rule and the second list construction rule. For example, the most likely pattern list can be constructed jointly according to the first list construction rule and the second list construction rule.

[0538] Through the technical solution of this embodiment, it can be ensured that the most likely pattern list is closely related to the sub-block features.
