[0001] The present disclosure relates to the field of image processing technologies, and in particular, to an image processing method, apparatus, electronic device, and storage medium. Background Art
[0002] In today's digital age, image processing technologies play a crucial role in numerous fields. Whether it is in computer vision, medical image analysis, film and television production, or satellite remote sensing image processing and other fields, various processing operations on images are widely involved. However, processing high-resolution images faces many challenges. Due to the huge number of pixels contained in high-resolution images, when processing them, the amount of computation will increase exponentially. This huge computing power overhead directly leads to difficulties in the smooth progress of the image processing process, which is specifically manifested as phenomena such as excessive processing delays, slow system responses, or even freezing and crashing. Therefore, how to improve the image processing rate of high-resolution images is an urgent problem to be solved at present. Summary of the Invention

[0005] Obtaining a target image and a target processing operation for the target image;
[0006] If the current resolution of the target image is greater than or equal to a preset resolution threshold, and the type of the target processing operation is a first type, reducing the resolution of the target image; the first type is a type of processing operation in which after processing operations are performed on different resolution versions of the same image, the processed different resolution versions are then uniformly adjusted to the same resolution, and the resulting images are the same;
[0007] Performing the target processing operation on the target image after reducing the resolution.
[0008] In a second aspect, the present disclosure further provides an image processing apparatus, including:
[0009] An obtaining module, configured to obtain a target image and a target processing operation for the target image;
[0010] An adjustment module, configured to reduce the resolution of the target image if the current resolution of the target image is greater than or equal to a preset resolution threshold and the type of the target processing operation is the first type; the first type is a type of processing operation in which after processing operations are performed on different resolution versions of the same image, the different resolution versions after the processing operations are uniformly adjusted to the same resolution, and the resulting images are the same.

[0017] The technical solution provided by the embodiments of the present disclosure has the following advantages compared with the prior art:
[0018] The technical solution provided by the embodiments of the present disclosure is configured to reduce the resolution of the target image if the current resolution of the target image is greater than or equal to a preset resolution threshold and the type of the target processing operation is the first type; the first type is a type of processing operation in which after processing operations are performed on different resolution versions of the same image, the different resolution versions after the processing operations are uniformly adjusted to the same resolution, and the resulting images are the same; and perform the target processing operation on the target image with the reduced resolution. Since the same image of different resolution versions processed by the first type of processing operation is the same after being adjusted to the same resolution. This indicates that performing the first type of processing operation on the image first and then adjusting the resolution is visually consistent with performing the first type of processing operation after adjusting the resolution first. However, compared with the solution of performing the first type of processing operation first and then adjusting the resolution, the computing power overhead of adjusting the resolution first and then performing the first type of processing operation is lower. The essence of the above technical solution is that when the target processing operation is the first type of processing operation, adjusting the image resolution first and then performing the target processing operation can reduce the computing power overhead of the target processing operation, improve the fluency of the image processing process, and reduce the probability of phenomena such as too high processing delay, slow system response, or even freezing and crashing.

[0025] In order to be able to more clearly understand the above objects, features, and advantages of the present disclosure, the following will further describe the solutions of the present disclosure. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.
[0026] Many specific details are set forth in the following description in order to fully understand the present disclosure, but the present disclosure can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all of the embodiments.
[0027] Figure 1 A flowchart of an image processing method provided for an embodiment of the present disclosure. This embodiment is applicable to the situation of performing image processing in a client. This method can be executed by an image processing device, which can be implemented in a software and / or hardware manner, and the device can be configured in an electronic device, such as a terminal, specifically including but not limited to a smart phone, a personal digital assistant, a tablet computer, a wearable device with a display screen, a desktop computer, a laptop computer, an all-in-one computer, a smart home device, etc. Alternatively, this embodiment is applicable to the situation of performing image processing in a server. This method can be executed by an image processing device, which can be implemented in a software and / or hardware manner, and the device can be configured in an electronic device, such as a server.
[0028] Such asFigure 1 As shown in Figure 1 , the method may specifically include:
[0029] S110. Obtain a target image and a target processing operation for the target image.
[0030] The target image may be, for example, an image to be processed and is the processing object of the target processing operation. Optionally, the target image may be an image taken or uploaded by a user, or an image downloaded from the network. The target image may be, for example, a static image, a dynamic image, or an image frame in a video.
[0031] The target processing operation is a specific processing operation for the target image. This application does not limit what the specific target processing operation is. Exemplarily, the target processing operation may be, for example, an import operation, a scaling operation, a cropping operation, a skin smoothing operation, a filter operation, a sharpening operation, an operation of adding text or adding stickers, etc., for the target image.
[0032] S120. If the current resolution of the target image is greater than or equal to a preset resolution threshold and the type of the target processing operation is the first type, reduce the resolution of the target image; the first type is a type of processing operation in which, after performing processing operations on different resolution versions of the same image, the different resolution versions after the processing operations are uniformly adjusted to the same resolution, and the resulting images are the same.
[0033] The current resolution of the target image may be, for example, the resolution of the target image at the moment when the target processing operation for the target image is detected. It should be noted that the target image has an original resolution. The original resolution of the target image is the image resolution when the target image is initially created or obtained. Since, during the process of processing the target image, it may involve one or more resolution adjustments to the target image, the current resolution of the target image may be equal to the original resolution of the target image or may not be equal to the original resolution of the target image when the target processing operation for the target image is detected.
[0034] The preset resolution threshold is a pre-specified resolution threshold used to measure whether the current resolution of the target image is too large. If the current resolution of the target image is greater than or equal to the preset resolution threshold, it means that the current resolution of the target image is too large. If the target processing operation is directly performed on the target image, it may cause huge computing power overhead. If the current resolution of the target image is less than the preset resolution threshold, it means that the current resolution of the target image is relatively small. If the target processing operation is directly performed on the target image, the computing power overhead is relatively small.
[0035] It should be noted that in some usage scenarios of the technical solution provided in this application, the resolution adjustment is mainly divided into two categories. One is to reduce the image resolution so that the resolution of the reduced image is lower than its original resolution, in order to reduce the computing power overhead of image processing. The other is to increase the image resolution so that the increased image resolution is the same as its original resolution, in order to ensure that the effect of image processing is better and reliable. In other words, in some usage scenarios of the technical solution of this application, when the current resolution of the target image is greater than or equal to the preset resolution threshold, it means that the current resolution of the target image is the original resolution of the target image. When the current resolution of the target image is less than the preset resolution threshold, it means that the current resolution of the target image is lower than the original resolution of the target image.
[0036] In practice, the types of processing operations can be set to include a first type and a second type.
[0037] The first type is a type of processing operation in which after performing processing operations on different resolution versions of the same image, the different resolution versions after the processing operations are then uniformly adjusted to the same resolution, and the resulting images are the same. Exemplarily, the processing operations belonging to the first type may include at least one of the following: rotation, flipping, translation, scaling, import, cropping, and color space conversion of the image, etc. Among them, "the resulting images are the same" may include, for example, that the resulting images are consistent in terms of details and color accuracy.
[0038] The second type is a type of processing operation in which after performing processing operations on different resolution versions of the same image, the different resolution versions after the processing operations are then uniformly adjusted to the same resolution, and the resulting images are different. Exemplarily, the processing operations belonging to the second type may include at least one of the following: adding a skin smoothing effect, a filtering effect, and sharpening. Among them, "the resulting images are different" may be manifested, for example, as differences in the resulting images in terms of details and / or color accuracy. Such differences may stem from changes in pixel values or may also be reflected in changes at the pixel level such as pixel arrangement and pixel - to - pixel relationships.
[0039] There are various specific implementation methods for this step, and this application does not limit it. Exemplarily, the implementation method of this step includes: if the type of the target processing operation is the first type, determining the size of the area on the current terminal screen for displaying the target image; based on the size of the area on the current terminal screen for displaying the target image, determining the target resolution value; adjusting the resolution of the target image to be equal to the target resolution value. Here, the terminal refers to the current terminal used to display the target image. Exemplarily, see Figure 2, in the terminal screen, if area 1 is used to display the target image, when it is determined that the resolution of the target image needs to be reduced, the specific resolution value to which the resolution of the target image needs to be reduced is determined in combination with the size of area 1. The purpose of this setting is to consider the display effect of the target image while reducing the resolution of the target image, so as to achieve the purpose of seeking a balance between ensuring the clear visual effect of the target image and reducing the computing power overhead.
[0040] In some embodiments, optionally, "determining the target resolution value based on the size of the area in the current terminal screen for displaying the target image" may include: determining the target resolution value based on the size of the area in the current terminal screen for displaying the target image and the target processing operation.
[0041] In practice, performing a target processing operation on the target image can be regarded as adjusting the parameters of the target image. The target processing operation includes information such as which parameters are adjusted and the adjustment amplitude. By setting the target processing operation to be considered when determining the target resolution value, the purpose is to estimate the visual performance of the image after performing the target processing operation on the target image by means of the target processing operation, so as to avoid the situation where the finally presented target image is distorted due to excessive reduction of the resolution of the target image.
[0042] In other embodiments, optionally, determining the target resolution value based on the size of the area in the current terminal screen for displaying the target image includes: in a preset plurality of resolution levels, determining the target level based on the size of the area in the current terminal screen for displaying the target image; each resolution level has a corresponding resolution value; and taking the resolution value corresponding to the target level as the target resolution value.
[0043] Exemplarily, assume that a total of 3 resolution levels are set, namely level 1, level 2, and level 3. The resolution value corresponding to level 1 is 1280×720, the resolution value corresponding to level 2 is 1920×1080, and the resolution value corresponding to level 3 is 3840×2160. If the current resolution of the target image is 7680×4320 and the resolution of the target image needs to be reduced, one of the above three levels can be selected as the target level according to the size of the area in the current terminal screen for displaying the target image. By adjusting the resolution of the target image to the resolution value corresponding to the target level, the purpose of reducing the resolution of the target image is achieved.
[0044] If resolution levels are preset, the rendering process can be pre-constructed or optimized for these resolution levels. When the resolution needs to be adjusted, it is possible to quickly select an appropriate rendering pipeline from the rendering pipelines corresponding to the preset resolution levels for rendering, without the need to construct or optimize the rendering pipeline in real time, which can improve the rendering speed and thus quickly obtain the target image after resolution adjustment.
[0045] Similarly, determining the target resolution value based on the size of the area on the current terminal screen for displaying the target image and the target processing operation may include: determining the target level among a preset plurality of resolution levels based on the size of the area on the current terminal screen for displaying the target image and the target processing operation; each resolution level has a corresponding resolution value; and taking the resolution value corresponding to the target level as the target resolution value. Such a setting can also improve the rendering speed and thus quickly obtain the target image after resolution adjustment.
[0046] S130. Perform a target processing operation on the target image after reducing the resolution.
[0047] In the above technical solution, if the current resolution of the target image is greater than or equal to the preset resolution threshold and the type of the target processing operation is the first type, the resolution of the target image is reduced; the first type is a type of processing operation in which, after performing processing operations on different resolution versions of the same image, the different resolution versions after the processing operations are uniformly adjusted to the same resolution, and the resulting images are the same; and a target processing operation is performed on the target image after reducing the resolution. Since the same image of different resolution versions processed by the first type of processing operation is the same after being adjusted to the same resolution. This shows that performing the first type of processing operation on the image first and then adjusting the resolution is visually consistent with adjusting the resolution first and then performing the first type of processing operation. However, compared with the solution of performing the first type of processing operation first and then adjusting the resolution, the computing power overhead of adjusting the resolution first and then performing the first type of processing operation is lower. The essence of the above technical solution is that when the target processing operation is the first type of processing operation, adjusting the image resolution first and then performing the target processing operation can reduce the computing power overhead of the target processing operation, improve the fluency of the image processing process, and reduce the probability of phenomena such as excessive processing delay, slow system response, and even freezing and crashing.
[0048] On the basis of the above technical solution, optionally, if the current resolution of the target image is greater than or equal to the preset resolution threshold, and the type of the target processing operation is the second type, perform the target processing operation on the target image; the second type is a type of processing operation obtained by performing processing operations on different resolution versions of the same image and then uniformly adjusting the processed different resolution versions to the same resolution. Here, "performing the target processing operation on the target image" means directly performing the target processing operation on the target image without adjusting the resolution of the target image.
[0049] Since the images obtained after adjusting different resolution versions of the same image processed by the second type of processing operation to the same resolution are different. This indicates that there are differences in the visual performance of the image between the scheme of first adjusting the image to a small resolution, performing the second type of processing operation on the small-resolution image, and then converting the small-resolution image into a large-resolution image, and the scheme of directly performing the second type of processing operation on the large-resolution image. In this case, to ensure that the high-resolution image has a better visual effect, the target processing operation should be directly performed on the high-resolution target image.
[0050] On the basis of the above technical solutions, optionally, the method may further include: in response to a save instruction for the processed target image, determining whether the resolution of the current target image is the same as the original resolution of the target image; the original resolution of the target image is the image resolution when the target image was initially created or acquired; the original resolution of the target image is greater than or equal to the preset resolution threshold; if the resolution of the current target image is different from the original resolution of the target image, adjust the resolution of the target image to be equal to the original resolution of the target image; save the target image adjusted to the original resolution. In some scenarios, optionally, "the resolution of the current target image is different from the original resolution of the target image" includes: the resolution of the current target image is less than the original resolution of the target image. The purpose of this setting is to save the processed target image as a high-resolution image when it is necessary to save the processed target image, so as to ensure that the saved image has high quality. It should also be noted that in practice, compared with low-resolution images, high-resolution images have finer details, higher clarity, and greater potential for post-processing. High-resolution images have a wider range of usage scenarios than low-resolution images, so high-resolution images are saved here.
[0051] Based on the above technical solutions, optionally, if the current resolution of the target image is less than the preset resolution threshold and the type of the target processing operation is the second type, adjust the resolution of the target image to the original resolution of the target image; the second type is a type of processing operation obtained by performing processing operations on different resolution versions of the same image and then uniformly adjusting the processed different resolution versions to the same resolution; perform the target processing operation on the target image at the original resolution.
[0052] The current resolution of the target image being less than the preset resolution threshold means that the current resolution of the target image is relatively low. Since there are differences in the visual performance of the image between the scheme of first adjusting the image to a small resolution, performing a second-type processing operation on the small-resolution image, and then converting the small-resolution image into a large-resolution image, and the scheme of directly performing a second-type processing operation on the large-resolution image. By setting that if the current resolution of the target image is less than the preset resolution threshold and the type of the target processing operation is the second type, adjust the resolution of the target image to the original resolution of the target image; perform the target processing operation on the target image at the original resolution. The purpose is to ensure that the finally obtained high-resolution image has a better visual effect, first convert the low-resolution image into a high-resolution image, and then directly perform the target processing operation on the high-resolution target image.
[0053] Optionally, if the current resolution of the target image is less than the preset resolution threshold and the type of the target processing operation is the first type, perform the target processing operation on the target image. Here, "performing the target processing operation on the target image" means directly performing the target processing operation on the target image without adjusting the resolution of the target image.
[0054] The following describes the solution provided by this application in combination with a specific scenario.
[0055] Suppose a user wishes to process a certain image. According to the image processing sequence, there are a total of 4 steps, namely importing the image into an image editing application, cropping the image, retouching the image, and saving the image. This image is the target image, and the first three steps above are three processing operations on the target image. During the execution of each of the first three steps, the operation involved in that step is the target processing operation. Among them, the type of the import operation corresponding to the first step, and the type of the cropping operation corresponding to the second step are both of the first type. The type of the retouching operation corresponding to the third step is of the second type. Suppose there are 3 resolution levels set, namely level 1, level 2, and level 3. The resolution value corresponding to level 1 is 1280×720, the resolution value corresponding to level 2 is 1920×1080, and the resolution value corresponding to level 3 is 3840×2160. The original resolution of this image is 7680×4320, and the preset resolution threshold is 7680×4320.
[0056] When the first step is executed, the current resolution of the image is equal to the original resolution, equal to the preset resolution threshold, and the type of the import operation corresponding to the first step is of the first type. Determine the target level among the three resolution levels. Suppose the target level determined this time is level 1. First, adjust the resolution of the image to 1280×720, and then display the image on the terminal screen. After the first step is completed, the resolution of the image is 1280×720.
[0057] When the second step is executed, the current resolution of the image is equal to the resolution of the image after the first step is completed, which is 1280×720, less than the preset resolution threshold, and the type of the import operation corresponding to the second step is of the first type. There is no need to adjust the resolution of the image. Directly crop the image and display the cropped image on the terminal screen. After the second step is completed, the resolution of the image is 1280×720.
[0058] When the third step is executed, the current resolution of the image is equal to the resolution of the image after the second step is completed, which is 1280×720, less than the preset resolution threshold, and the type of the import operation corresponding to the third step is of the second type. Adjust the resolution of the image to be equal to the original resolution of the image. After adjustment, the resolution of the image is 7680×4320. Retouch the image and display the retouched image on the terminal screen. After the third step is completed, the resolution of the image is 7680×4320.
[0059] When the fourth step is executed, the current resolution of the image is equal to the resolution of the image after the third step is completed, which is 7680×4320 and equal to the original resolution of the image. The image is directly saved. The resolution of the saved image is 7680×4320.
