[0001] This disclosure relates to special effects processing technology, and more particularly to a special effects processing method, apparatus, electronic device, and storage medium. Background Technology

[0002] With the development of multimedia technology, various special effects are being applied to videos to enrich their presentation. A typical approach is to add a variety of special effects objects to the video.

[0003] In related technologies, pre-set special effects objects are usually overlaid directly on image frames in the video. This special effects processing method makes the display of special effects objects in the image frames look rather abrupt, affecting the user experience. Summary of the Invention

[0036] Figure 1 This is a flowchart illustrating a special effects processing method provided in an embodiment of the present disclosure. This embodiment is applicable to situations where a portion of a special effects object is blurred. The method can be executed by a special effects processing device, which can be implemented in the form of software and / or hardware. Optionally, it can be implemented by an electronic device, such as a mobile terminal, a PC, or a server.

[0037] like Figure 1 As shown, the method in this embodiment may specifically include:

[0038] S110, In response to the effect addition operation, obtain the image to be processed and the effect object to be added.

[0039] The effects addition operation is used to add effects objects to the image to be processed.

[0040] Optionally, the effect addition operation can be an effect triggering operation for the effect to be added. For example, an effect triggering operation for the effect to be added can be: triggering a pre-set effect enabling control corresponding to the effect to be added, or inputting an effect enabling control command corresponding to the effect to be added, such as sound and / or gesture. Typically, the effect enabling control can be represented by an effect icon corresponding to the effect to be added. The effect icon can be displayed as text and / or an image.

[0041] The image to be processed can be understood as an image to be processed with special effects, or an image obtained after enabling the special effects to be added. Optionally, the image to be processed can be an image taken with the special effects to be added, or an image uploaded with the special effects to be added. It should be noted that the image content of the image to be processed is not limited in this embodiment.

[0042] The special effect object to be added can be understood as an object corresponding to the special effect to be added and used to add to the image to be processed. In this embodiment of the disclosure, the special effect object can take many forms. For example, the special effect object can be a decoration or accessory displayed in the image to be processed. For example, the special effect object can be at least one of objects such as a watch, bracelet, necklace, and earrings. It is understood that there can be one or more special effect objects to be added.

[0043] S120. If the image to be processed includes an object corresponding to the special effect object, determine the blurred rendering area of ​​the special effect object based on the special effect object and the object.

[0044] The target object can be understood as an object displayed in the image to be processed that is associated with the special effect object. The target object may include, but is not limited to, a pre-defined type of image subject in the image to be processed. The image subject can be a region of interest in the image to be processed. For example, the image subject can be a scene subject such as a person, animal, plant, or building in the image to be processed. The image subject can also be part or all of a scene subject. For example, the image subject can be at least one of the following parts of a person: hand (e.g., fingers or wrist), neck, head, ear, nose, leg, and foot (e.g., toes or ankle). Optionally, the image subject can also be a foreground or background region in the image to be processed. It is understood that the image to be processed may include one or more target objects corresponding to the special effect object.

[0045] In practical applications, the content of the images to be processed is diverse. To ensure the effectiveness of special effects, the special effect objects can be displayed in correspondence with preset object types. Therefore, if the image to be processed includes an object corresponding to the special effect object, the special effect object can be processed and displayed separately.

[0046] Optionally, a correspondence between effect objects and their corresponding objects can be pre-defined. After acquiring the image to be processed, the image is detected to determine whether it contains an object corresponding to the effect object. Specifically, the main subject in the image to be processed is detected to determine whether a preset type of main subject exists. If so, the preset type of main subject is used as the object corresponding to the effect object. Optionally, the detection of the main subject in the image to be processed includes: detecting the main subject in the image to be processed based on an image detection model, wherein the image detection model is trained based on a pre-established artificial intelligence model. The artificial intelligence model may include, but is not limited to, machine learning models or deep learning models, for example, a convolutional neural network.

[0047] The blurred rendering area can be understood as the area to be blurred and then rendered. In this embodiment, the blurred rendering area of ​​the special effect object can be the entire area or a part of the special effect object. Optionally, determining the blurred rendering area of ​​the special effect object based on the special effect object and the acting object includes: determining the connection area between the special effect object and the acting object, and using the connection area as the blurred rendering area of ​​the special effect object. For example, the connection area can be the area connecting the edge of the special effect object and the edge of the acting object. For example, in some scenarios, a part of the special effect object may be occluded by the acting object. Suppose that the visible part after the special effect object is applied to its corresponding acting object is called the display area, and the part of the special effect object occluded by the acting object is called the occluded area. In this case, the blurred rendering area of ​​the special effect object can be a part of the display area of ​​the special effect object adjacent to the occluded area.

[0048] S130. Blur the rendered area, apply the blurred effect object to the target object to obtain the effect image, and display the effect image.

[0049] In this context, blurring can be understood as weakening the pixels in the blurred rendering area. The special effects image can be understood as the image obtained after being added to the image to be processed. Specifically, each pixel in the blurred rendering area can be uniformly or differentially processed to give the pixels in the blurred rendering area a blurred effect. Blurring the blurred rendering area of ​​the special effects object can make the display effect of the special effects object softer, thereby improving the special effects image obtained after the special effects object acts on the applied object.

[0050] In this embodiment of the disclosure, there are multiple ways to blur the rendered area of ​​the special effects object, and the specific method used can be set according to actual needs.

[0051] Optionally, blurring the blurred rendering area includes: blurring the blurred rendering area according to the arrangement information of each pixel in the blurred rendering area. For example, the edge pixels of the blurred rendering area can be used as starting pixels, and the pixels in the blurred rendering area can be blurred in units of pixel rows or pixel columns. Wherein, the pixel values ​​of each pixel in the same pixel row are the same or can change according to a preset variation method. Similarly, the pixel values ​​of each pixel in the same pixel column are the same, or can change according to a preset variation method.

[0052] Furthermore, the way to blur the pixels in the blurred rendering area can be by adjusting the pixel values ​​of the pixels in the blurred rendering area using preset pixel values, or by adjusting the transparency of the pixels in the blurred rendering area, etc.

[0053] To ensure the real-time processing of special effects, optionally, the special effects image is displayed in real time after it is obtained.

[0054] The technical solution of this disclosure, in response to an effect addition operation, automatically acquires the image to be processed and the effect object to be added, enabling simple and convenient activation of effects. Then, if the image to be processed includes an object corresponding to the effect object, the blurred rendering area of ​​the effect object is determined based on the effect object and the object, allowing for targeted generation of the blurred rendering area and ensuring the desired effect of both the effect object and the object. Finally, the blurred rendering area is blurred, and the blurred effect object is applied to the object to obtain the effect image. Displaying the effect image allows for intuitive observation of the effect, solving the technical problem of stiff effect display. It eliminates the need for complex and professional manual processing; simple user-triggered operations are sufficient for automated processing and displaying the blurred effect, broadening its applicability. Furthermore, it enhances the depth of field of the image, increasing its aesthetic appeal and improving the user experience.

[0055] Figure 2 This is a flowchart illustrating another special effects processing method provided in this embodiment. Based on the above embodiments, this embodiment further refines how to determine the blurred rendering area. Optionally, determining the blurred rendering area of ​​the special effects object based on the special effects object and the object acting on it includes: determining an occlusion model corresponding to the special effects object, wherein the occlusion model is used to occlude the area of ​​the special effects object occluded by the object acting on it; determining a blurring model corresponding to the object acting on it; and determining the blurred rendering area of ​​the special effects object based on the blurring model and the occlusion model. For detailed implementation, please refer to the description of this embodiment. Technical features that are the same as or similar to those in the foregoing embodiments will not be repeated here.

[0056] like Figure 2 As shown, the method in this embodiment may specifically include:

[0057] S210, In response to the effect addition operation, obtain the image to be processed and the effect object to be added.

[0058] S220. If the image to be processed includes an object corresponding to the special effect object, determine the occlusion model corresponding to the special effect object.

[0059] Among them, the occlusion model is used to occlude the area of ​​the special effect object that is occluded by the applied object.

[0060] Understandably, to ensure the occlusion effect of the occlusion model on the special effects object, the occlusion model can correspond to the object model of the special effects object. Optionally, determining the occlusion model corresponding to the special effects object includes: determining the object model of the special effects object, and obtaining the occlusion model corresponding to the special effects object based on the object model. The object model can be understood as a 3D model of the special effects object.

[0061] In this embodiment of the disclosure, the style of the special effects object can be diverse. For example, an occlusion model corresponding to each special effects object or each type of special effects object can be pre-constructed. Optionally, an occlusion model corresponding to the special effects object can be constructed based on the object model of the special effects object, or an occlusion model corresponding to the special effects object can be constructed based on the object acting on the special effects object, etc.

[0062] Optionally, obtaining the occlusion model corresponding to the special effects object based on the object model includes: obtaining a pre-constructed occlusion model corresponding to the object model as the occlusion model corresponding to the special effects object. For example, a mapping relationship between the object model of the special effects object and the occlusion model can be established. For instance, the identifier of the object model of the special effects object can be stored in correspondence with the identifier of the occlusion model. Specifically, the identifier of the occlusion model can be determined based on the mapping relationship and the identifier of the object model of the special effects object; then, the occlusion model can be obtained based on the identifier of the occlusion model; and the occlusion model corresponding to the special effects object can be determined based on the obtained occlusion model.

[0063] Specifically, determining the occlusion model corresponding to the special effects object based on the acquired occlusion model includes: using the acquired occlusion model as the occlusion model corresponding to the special effects object, or receiving a first adjustment operation on the acquired occlusion model and using the adjusted occlusion model as the occlusion model corresponding to the special effects object. The first adjustment operation includes adjusting information such as the size and / or shape of the occlusion model.

[0064] In practical applications, the objects to be processed in the image often exhibit various differences. Optionally, an occlusion model corresponding to the effect object is generated based on multiple edge points of the effect object. The advantage of this setting is that it allows for a higher degree of matching between the effect object and the object being processed, resulting in a better relative display effect between the two.

[0065] Before generating an occlusion model corresponding to the special effect object based on multiple edge points of the target object, the target object corresponding to the special effect object in the image to be processed can be determined first. Then, the edges of the target object are detected to obtain multiple edge points of the target object. There are various ways to detect the edges of the target object; for example, the edges of the target object can be detected based on a pre-trained edge detection model. The edge detection model can be an artificial intelligence model. To ensure the edge detection model's effectiveness for the target object, the edge detection model can be trained separately for each type of target object. Specifically, the edge detection model can be trained based on a sample image and a corresponding labeled image. The standard image is a sample image labeled with the sample edge points of the target object.

[0066] When the image to be processed is a 3D image, specifically, an occlusion model corresponding to the object can be constructed using multiple edge points of the object as vertices. When the image to be processed is a 2D image, the 2D coordinates of the multiple edge points of the object can be first converted into 3D coordinates, and then the occlusion model corresponding to the object can be constructed using the 3D coordinates as vertices. Optionally, there are several ways to convert the 2D coordinates of the multiple edge points of the object into 3D coordinates. For example, a preset depth value can be added to each edge point to obtain its 3D coordinates. For example, the preset depth value can be -1.

[0067] To ensure that the occlusion model matches the size of the effect object and the object being processed, and also matches their display position in the image to be processed, optionally, generating an occlusion model corresponding to the effect object based on multiple edge points of the effect object includes: mapping the screen of multiple edge points of the effect object onto the near clipping plane of the camera to obtain a projection patch, and determining the occlusion model corresponding to the effect object based on the projection patch.

[0068] Specifically, for each edge point, based on the screen coordinates of the edge point on the display screen and the size ratio between the near clipping plane and the display screen in the model space, the mapping point corresponding to the edge point on the near clipping plane is determined. Then, the mapping points corresponding to multiple edge points are used as vertices for rendering to obtain the projection surface corresponding to the edge point.

[0069] The near clipping plane is a pre-defined clipping plane in the model space, and its size ratio to the display screen is fixed. In other words, the coordinates of points on the near clipping plane can be matched with the coordinates of points on the display screen according to the size ratio between the near clipping plane and the display screen.

[0070] Further, determining the occlusion model corresponding to the special effects object based on the projection surface includes: determining the occlusion model corresponding to the special effects object based on the size ratio between the projection surface and the near-cropping surface and the display screen. Specifically, the projection surface can be enlarged or reduced according to the size ratio between the near-cropping surface and the display screen to obtain the occlusion model corresponding to the special effects object.

[0071] S230. Determine the blurring model corresponding to the target object, and determine the blurring rendering area of ​​the special effect object based on the blurring model and the occlusion model.

[0072] The blurring model can be understood as a model used to determine the blurring rendering area of ​​the special effects object. Optionally, a pre-established reference model corresponding to the effect object is obtained, and the blurring model corresponding to the effect object is determined based on the reference model. For example, the shape and size of the effect object can be determined, and then a reference model corresponding to the effect object can be established based on the shape and size of the effect object. The size of the effect object can be the size of a single effect object, or the average size of multiple effect objects, etc.

[0073] Specifically, determining the blurring model corresponding to the target object based on the reference model includes: using the acquired reference model as the blurring model corresponding to the special effects object, or receiving a second adjustment operation on the acquired reference model and using the adjusted reference model as the blurring model corresponding to the special effects object. The second adjustment operation includes adjusting information such as the size and / or shape of the reference model. The advantage of this setup is that it ensures the blurring model matches the target object.

[0074] Optionally, determining the blurred model corresponding to the target object includes: enlarging the occlusion model to obtain the blurred model. Specifically, the occlusion model can be enlarged proportionally according to a preset enlargement ratio to obtain the blurred model. The specific value of the enlargement ratio can be set according to actual conditions and is not specifically limited here. For example, the edge pixels of the occlusion model can be used as reference pixels to enlarge the occlusion model to obtain the blurred model. In other words, each edge pixel of the occlusion model can be expanded outward by a preset number of pixels to obtain the blurred model.

[0075] In this embodiment of the disclosure, in order to ensure the interaction effect between the image to be processed and the special effects object, and to reduce the interference of the virtual model on the image effect, the model display information of the blurred model can be determined based on the image information of the image to be processed. Optionally, for each model pixel in the blurred model, the pixel value of the model pixel is determined based on the pixel value of the image pixel in the image to be processed corresponding to the model pixel. The model pixel can be the pixel to be processed in the blurred model.

[0076] Specifically, determining the pixel value of the model pixel based on the pixel value of the image pixel corresponding to the model pixel in the image to be processed can include: using the pixel value of the image pixel corresponding to the model pixel in the image to be processed as the pixel value of the model pixel, or adjusting the pixel value of the image pixel corresponding to the model pixel in the image to be processed to obtain the pixel value of the model pixel. The advantage of this setting is that it can weaken the display effect of the blurred model in the image to be processed, achieving a visualization effect of hiding the blurred model within the image to be processed.

[0077] In this embodiment of the disclosure, the size of the blurred model is not smaller than that of the occlusion model. Optionally, determining the blurred rendering area of ​​the special effects object based on the blurred model and the occlusion model includes: determining the non-overlapping area of ​​the blurred model and the occlusion model, and using the non-overlapping area as the blurred rendering area of ​​the special effects object. For example, the centers of the blurred model and the occlusion model can be aligned to determine the non-overlapping area. When the blurred model is obtained by enlarging the occlusion model, the expanded area of ​​the blurred model relative to the occlusion model is the blurred rendering area of ​​the special effects object.

[0078] The advantage of using the non-overlapping areas of the blurred model and the occluding model as the blurred rendering area of ​​the special effects object is that at least a portion of the visual area of ​​the special effects object can be blurred without processing the part of the special effects object that is occluded by the occluding model, reducing invalid processing, improving the efficiency of blurring processing, and ensuring the visualization effect of blurring the special effects object.

[0079] S240. Blur the rendered area, apply the blurred effect object to the target object to obtain the effect image, and display the effect image.

[0080] The technical solution of this disclosure, through an occlusion model corresponding to the special effects object, can determine the visualization effect of the special effects object on the target object. By using a blurring model and an occlusion model corresponding to the target object, a blurring rendering area that matches both the special effects object and the target object can be specifically determined, thereby ensuring the blurring effect of the special effects object and improving the special effects overall.

[0081] Figure 3 This is a flowchart illustrating another special effects processing method provided in this embodiment. Based on the above embodiments, this embodiment further refines how to perform blurring processing on the blurred rendering area. Optionally, the blurring processing of the blurred rendering area includes: for the pixel to be blurred in the blurred rendering area, determining a first pixel value in the blurred model and a second pixel value in the special effects object; and determining a target pixel value for the pixel to be blurred based on the first pixel value and the second pixel value. For detailed implementation, please refer to the description of this embodiment. Technical features that are the same as or similar to those in the foregoing embodiments will not be repeated here.

[0082] like Figure 3 As shown, the method in this embodiment may specifically include:

[0083] S310, In response to the effect addition operation, obtain the image to be processed and the effect object to be added.

[0084] S320. If the image to be processed includes an object corresponding to the special effect object, determine the occlusion model corresponding to the special effect object.

[0085] S330. Determine the blurring model corresponding to the target object, and determine the blurring rendering area of ​​the special effect object based on the blurring model and the occlusion model.

[0086] S340. For the pixels to be blurred in the blurred rendering area, determine the first pixel value of the pixel to be blurred in the blurred model and the second pixel value of the pixel to be blurred in the effect object.

[0087] Here, the pixel to be blurred can be understood as the pixel in the blurred rendering area that needs to be blurred. The first pixel value can be understood as the pixel value of the pixel to be blurred in the blurred model. As mentioned earlier, the display information of the blurred model can be consistent with the display information of the image to be processed. For example, the first pixel value can be understood as the pixel value of the pixel to be blurred in the image to be processed. The second pixel value can be understood as the pixel value of the pixel to be blurred in the effect object.

[0088] S350. Based on the first pixel value and the second pixel value, determine the target pixel value of the pixel to be blurred.

[0089] In this embodiment of the disclosure, the first pixel value and the second pixel value can be fused to obtain the target pixel value of the pixel to be blurred. There are various ways to fuse the first pixel value and the second pixel value, such as fusing the first pixel value and the second pixel value based on a preset weight value.

[0090] Optionally, the transparency of the pixel to be blurred in the blurring model is determined, and then, based on the transparency, the first pixel value, and the second pixel value, the target pixel value of the pixel to be blurred is determined. By adjusting the transparency of the blurring model, the display effect of the first pixel value on the pixel to be blurred is adjusted, and then the display effect of the second pixel value of the effect object is adjusted by the first pixel value, thereby achieving the blurring processing of the pixel to be blurred.

[0091] In this embodiment, there are multiple ways to determine the transparency of the pixel to be blurred in the blurred model. Optionally, the viewing information corresponding to the pixel to be blurred and the normal information at the pixel to be blurred in the blurred model are determined; the transparency of the pixel to be blurred in the blurred model is determined based on the viewing information and the normal information. The advantage of this setting is that it makes the blurring effect more in line with visual habits and ensures the visualization effect of the pixel to be blurred in the blurred rendering area.

[0092] In this process, the normal information at the pixel to be blurred in the blurred model can be determined using geometric methods. For example, first determine the tangent at the pixel to be blurred in the blurred model, and then determine the normal at the pixel to be blurred in the blurred model based on the tangent. Optionally, the blurred model can be cut based on the pixel to be blurred to obtain a cross-section of the model corresponding to the pixel to be blurred, and then the normal information at the pixel to be blurred can be calculated based on the cross-section of the model. Specifically, a normal algorithm for calculating the pixel to be blurred is used based on the shape of the cross-section of the model, and then the normal information at the pixel to be blurred is calculated based on the normal algorithm. To ensure the efficiency of normal information calculation, a normal algorithm corresponding to the shape of the cross-section of the model can be preset. Taking an elliptical cross-section of the model as an example, the normal information at the pixel to be blurred can be determined by the ratio of the major axis to the minor axis.

[0093] Optionally, the transparency of the pixel to be blurred in the blurring model is determined based on the line-of-sight information and normal information, specifically including: multiplying the line-of-sight information and normal information to obtain a fusion value, and determining the transparency of the pixel to be blurred in the blurring model based on the fusion value.

[0094] For example, the blend value can be used as the transparency of the pixel to be blurred in the blurred model, or the blend value can be adjusted based on preset adjustment parameters to obtain the transparency of the pixel to be blurred in the blurred model. The preset adjustment parameters can be understood as pre-set parameters used to adjust the size of the blend value. These adjustment parameters can be made available to the user for independent setting. Furthermore, the system can receive parameter setting operations for the preset adjustment parameters, and adjust the blend value based on the set parameter value to obtain the transparency of the pixel to be blurred in the blurred model. The method of adjusting the blend value based on the set parameter value can be, for example, multiplying the set parameter value by the blend value.

[0095] Optionally, determining the transparency of the pixels to be blurred in the blurred model includes: determining the transparency of the pixels to be blurred in the blurred model based on the grayscale values ​​corresponding to the pixels to be blurred in the blurred model. For example, the grayscale values ​​corresponding to the model pixels in the blurred model can be preset, and then the grayscale values ​​corresponding to the pixels to be blurred in the blurred model can be determined. Alternatively, the grayscale values ​​of the pixels to be blurred in the blurred rendering area can be preset. For example, the grayscale values ​​corresponding to the pixels to be blurred can be used as the transparency of the pixels to be blurred in the blurred model. The grayscale values ​​of the pixels to be blurred in the blurred rendering area can gradually change according to the extension direction of the effect object, from dark to light or from light to dark. For example, the grayscale values ​​corresponding to the pixels to be blurred closer to the occluding model are lighter, and the grayscale values ​​corresponding to the pixels to be blurred farther from the occluding model are darker. It is understood that the specific values ​​of the grayscale values ​​corresponding to the pixels to be blurred can be set according to actual needs and are not specifically limited here.

[0096] S360. Apply the blurred special effects object to the target object to obtain the special effects image, and display the special effects image.

[0097] The technical solution of this embodiment achieves the blurring of the rendering area of ​​the special effects object by fusing the first pixel value of the pixel to be blurred in the blurring model and the second pixel value of the pixel to be blurred in the special effects object, thus making the display effect of the special effects object more layered. Since the blurring model corresponds to the target object, the blurring effect of the special effects object is more closely matched with the target object.

[0098] Figure 4 This is a schematic diagram of the structure of a special effects processing device provided in an embodiment of this disclosure. Figure 4 As shown, the special effects processing device includes: a special effects triggering module 410, a blurring area determination module 420, and a special effects display module 430.

[0099] The system includes a special effects triggering module 410, which is used to acquire the image to be processed and the special effects object to be added in response to the special effects addition operation; a blurring region determination module 420, which is used to determine the blurring rendering region of the special effects object based on the special effects object and the special effects object when the image to be processed includes an object corresponding to the special effects object; and a special effects display module 430, which is used to blur the blurring rendering region, apply the blurred special effects object to the object to obtain the special effects image, and display the special effects image.

[0100] The technical solution of this disclosure, in response to an effect addition operation, automatically acquires the image to be processed and the effect object to be added, enabling simple and convenient activation of effects. Then, if the image to be processed includes an object corresponding to the effect object, the blurred rendering area of ​​the effect object is determined based on the effect object and the object, allowing for targeted generation of the blurred rendering area and ensuring the desired effect of both the effect object and the object. Finally, the blurred rendering area is blurred, and the blurred effect object is applied to the object to obtain the effect image. Displaying the effect image allows for intuitive observation of the effect, solving the technical problem of stiff effect display. It eliminates the need for complex and professional manual processing; simple user-triggered operations are sufficient for automated processing and displaying the blurred effect, broadening its applicability. Furthermore, it enhances the depth of field of the image, increasing its aesthetic appeal and improving the user experience.
