[0040] Please see Figure 1 , Figure 1 This diagram illustrates an application environment for the video processing method provided in this embodiment of the invention. Electronic device 100 and server 200 are located in a network. Electronic device 100 can communicate with server 200 to achieve data interaction between them. Alternatively, the electronic device 100 and server 200 can connect via WIFI, ZigBee, or 2G / 3G / 4G / 5G, and this is not limited to any particular method.

[0041] Please see Figure 2 , Figure 2 This diagram illustrates a flow chart of a video processing method provided by an embodiment of the present invention. This video processing method can be applied to an electronic device. The electronic device is communicatively connected to a server, which stores the correspondence between scene types and effect parameter configuration information. The specific flow of this embodiment is described below using an electronic device as an example. The following section focuses on... Figure 3The flow shown is described in detail, and the video processing method can specifically include the following steps:

[0042] Step S110: Obtain the to-be-processed video, the effect parameter configuration information corresponding to each frame of to-be-processed image, and the image information of each frame of to-be-processed image from the server.

[0043] The to-be-processed image is an image in the to-be-processed video that needs to be processed, and the effect parameter configuration information corresponding to each frame of to-be-processed image is determined according to the scene type of each frame of to-be-processed video and the corresponding relationship. Each frame of to-be-processed image and the scene type of each frame of to-be-processed image are obtained by identifying each frame of image of the to-be-processed video by the server.

[0044] In some embodiments, the server can be connected with a plurality of acquisition devices, the acquisition device end is used for acquiring a video, and the acquired video is sent to the server. The server stores a plurality of videos. The electronic device can receive a visual effect processing instruction and send the visual effect processing instruction to the server. The server determines a to-be-processed video from the plurality of videos according to the visual effect processing instruction. The server identifies each frame of image in the to-be-processed video, obtains a plurality of frames of to-be-processed images, the scene type of each frame of to-be-processed image, and the image information of each frame of to-be-processed image, and determines the effect parameter configuration information corresponding to each frame of to-be-processed image according to the scene type of each frame of to-be-processed video and the corresponding relationship. The server sends the to-be-processed video, the plurality of frames of to-be-processed images, the effect parameter configuration information corresponding to each frame of to-be-processed image, and the image information of each frame of to-be-processed image to the electronic device, so that the electronic device performs blur processing on each frame of to-be-processed image according to the effect parameter configuration information corresponding to each frame of to-be-processed image and the image information. The to-be-processed video can be a live video, an explanation video, a promotional video, a demonstration video, and the like, which is not limited herein.

[0045] For example, the server stores a corresponding relationship between the scene type and the effect parameter configuration information, as shown in Table 1. If the scene type of the to-be-processed image 1 is scene type 1, the effect parameter configuration information corresponding to the to-be-processed image 1 is effect parameter configuration information 1. If the scene type of the to-be-processed image 1 is scene type 2, the effect parameter configuration information corresponding to the to-be-processed image 1 is effect parameter configuration information 2.

[0047]

[0048]

[0049] In some embodiments, the user can configure the effect parameters in the server according to the visual effects exhibited by different scenes in actual application, and the server stores the correspondence between the scene types and the effect parameter configuration information, which can include the blur degree parameter, the blur radius parameter, and the system support parameter, without limitation.

[0050] It should be noted that each frame of the to-be-processed image is an image in the to-be-processed video that needs to be blurred, and thus, if each frame of the to-be-processed video needs to be blurred, the total number of frames of all the to-be-processed images is equal to the total number of frames of the to-be-processed video; if only part of the images in the to-be-processed video need to be blurred, the total number of frames of all the to-be-processed images is less than the total number of frames of the to-be-processed video.

[0051] In some embodiments, the server is provided with a scene recognition system, the server identifies each frame of the to-be-processed image through the scene recognition system, obtains the multiple frames of to-be-processed images, the scene type of each frame of the to-be-processed image, and the image information of each frame of the to-be-processed image, and sends the multiple frames of to-be-processed images, the scene type of each frame of the to-be-processed image, and the image information of each frame of the to-be-processed image to the electronic device.

[0052] Step S120: blurring each frame of the to-be-processed image according to the effect parameter configuration information corresponding to each frame of the to-be-processed image and the image information to obtain all the visual effect images, so as to obtain the video with visual effects.

[0053] In some embodiments, the electronic device can blur each frame of the to-be-processed image according to the effect parameter configuration information corresponding to each frame of the to-be-processed image and the image information sent by the server to obtain all the visual effect images, where the blurring manner of each frame of the to-be-processed image can be Gaussian blurring, mean blurring, or the like without limitation. The visual effect in the visual effect image can be a frosted glass effect, a mosaic effect, or the like without limitation.

[0054] It should be noted that the frosted glass effect is a soft and blurred visual effect on the image similar to frosted glass.

[0055] It can be understood that the effect parameter configuration information corresponding to each frame of the to-be-processed image is determined by the scene type of each frame of the to-be-processed image, and each frame of the visual effect image is blurred according to the effect parameter configuration information corresponding to each frame of the to-be-processed image, and thus the visual effects of the visual effect images of different scene types are different, thereby improving the richness of the visual effects of the video.

[0056] In some embodiments, the video to be processed includes source video images in addition to the image to be processed. After all visual effect images are obtained, the source video images and the visual effect images are sorted according to the time stamps of each frame of image to obtain a video with visual effects.

[0057] In some embodiments, the electronic device is provided with a graphics processing unit (GPU). The electronic device can perform blur processing on each frame of image to be processed according to the effect parameter configuration information corresponding to each frame of image to be processed and the image information, to obtain all visual effect images. The blur processing on the image to be processed is completed in the GPU, and the image to be processed does not need to be sent to the central processing unit (CPU) for blur processing. The CPU obtains a video with visual effects, and sends the video to the GPU for video output and display. In this way, the image to be processed between the CPU and the GPU can be avoided, and the efficiency of video processing can be improved.

[0058] In some embodiments, the effect parameter configuration information corresponding to different scene types can be configured into an application programming interface (API) corresponding to the scene type, and the API corresponding to the scene type of the image to be processed can be directly called when the image to be processed is blurred to obtain a visual effect image. The corresponding API can be modified according to the actual use when the effect of the visual effect image is modified, and the visual effect image with the corresponding effect can be obtained, so as to meet the customized visual experience.

[0059] The video processing method provided by the embodiment of the application obtains a video to be processed, effect parameter configuration information corresponding to each frame of image to be processed, and image information of each frame of image to be processed from a server. The effect parameter configuration information corresponding to each frame of image to be processed is determined according to the scene type of the image to be processed and the corresponding relationship. Each frame of image to be processed is obtained by identifying the video to be processed by the server. Each frame of image to be processed is blurred according to the effect parameter configuration information corresponding to each frame of image to be processed and the image information, to obtain all visual effect images, so as to obtain a video with visual effects. The corresponding image to be processed is blurred according to the effect parameter configuration information corresponding to the scene type of each frame of image to be processed, so that the visual effects of the visual effect images of different scene types are different, thereby improving the richness of the visual effects of the video.

[0060] In some embodiments, referring to Figure 3 , step S120 further includes the following steps:

[0061] Step S121: blur processing is performed on the corresponding to-be-processed image according to the effect parameter configuration information and the image information respectively, to obtain all to-be-fused images.

[0062] In some embodiments, the electronic device can perform blur processing on the to-be-processed image by using a Gaussian blur algorithm. The electronic device can scale the to-be-processed image, and perform Gaussian blur processing on the scaled to-be-processed image, so that the performance consumption of the Gaussian blur algorithm can be reduced.

[0063] In some embodiments, the electronic device stores a scaling condition. If the image information satisfies the scaling condition, scaling processing is performed on the corresponding to-be-processed image to obtain a corresponding scaled image, Gaussian blur processing is performed on the scaled image according to the effect parameter configuration information to obtain a corresponding first Gaussian blur image, and up-sampling is performed on the first Gaussian blur image to obtain a corresponding to-be-fused image. If the image information does not satisfy the scaling condition, Gaussian blur processing is performed on the corresponding to-be-processed image according to the effect parameter configuration information to obtain a corresponding second Gaussian blur image, and up-sampling is performed on the second Gaussian blur image to obtain a corresponding to-be-fused image. It can be understood that the to-be-fused image is obtained by performing blur processing on the to-be-processed image, and thus the to-be-fused image is the to-be-processed image with a blur effect.

[0064] In some embodiments, the electronic device can perform Gaussian blur processing on the to-be-processed image by using a Gaussian blur algorithm. The blur calculation is first performed on the to-be-processed image or the scaled image in the long direction, and then the blur calculation is performed on the to-be-processed image or the scaled image in the wide direction, to obtain the first Gaussian blur image or the second Gaussian blur image.

[0065] In some embodiments, the scaling conditions stored in different electronic devices can be different or the same. The scaling condition stored in the electronic device can be determined according to the performance of the GPU provided in the electronic device.

[0066] In some embodiments, the image information of each to-be-processed image includes an image resolution. If the image resolution is greater than a preset resolution, it is indicated that the image information satisfies the scaling condition. If the image resolution is less than the preset resolution, it is indicated that the image information does not satisfy the scaling condition.

[0067] For example, the preset resolution is 1920*1080. It is assumed that the image resolution of the to-be-processed image 1 is 2560*1440, and the image resolution of the to-be-processed image 1 is greater than the preset resolution. Therefore, the image information of the to-be-processed image 1 satisfies the scaling condition. It is assumed that the image resolution of the to-be-processed image 1 is 1280*720, and the image resolution of the to-be-processed image 1 is less than the preset resolution. Therefore, the image information of the to-be-processed image 1 does not satisfy the scaling condition.

[0068] In some embodiments, the electronic device stores a preset scaling ratio, and if the image information satisfies a scaling condition, the corresponding to-be-processed image is scaled according to the preset scaling ratio to obtain a corresponding scaled image.

[0069] In some embodiments, the preset resolution includes a preset width resolution and a preset height resolution, the image resolution includes a width image resolution and a height image resolution, a ratio of the width image resolution to the preset width resolution is calculated to obtain a width scaling ratio, a ratio of the height image resolution to the preset height resolution is calculated to obtain a height scaling ratio, the greater of the width scaling ratio and the height scaling ratio is determined as a target scaling ratio, and the corresponding to-be-processed image is scaled according to the target scaling ratio to obtain a corresponding scaled image.

[0070] For example, the preset resolution is 1920*1080, the preset width resolution is 1080, the preset height resolution is 1920, the image resolution of the to-be-processed image 1 is 4096*2160, the width image resolution is 2160, and the height image resolution is 4096. A ratio of the width image resolution to the preset width resolution is calculated to obtain a width scaling ratio of 2 (2160 / 1080=2), a ratio of the height image resolution to the preset height resolution is calculated to obtain a height scaling ratio of 2.13 (4096 / 1920=2.13), the height scaling ratio (2.13) is determined as the target scaling ratio, the to-be-processed image 1 is scaled according to the target scaling ratio to obtain a corresponding scaled image, and the resolution of the scaled image is 1920*1014 (1920=4096 / 2.13; 1014=2160 / 2.13).

[0071] In some embodiments, the preset resolution includes a preset width resolution and a preset height resolution, the image resolution includes a width image resolution and a height image resolution, a ratio of the preset width resolution to the width image resolution is calculated to obtain a width scaling ratio, a ratio of the preset height resolution to the height image resolution is calculated to obtain a height scaling ratio, the smaller of the width scaling ratio and the height scaling ratio is determined as a target scaling ratio, and the corresponding to-be-processed image is scaled according to the target scaling ratio to obtain a corresponding scaled image.

[0072] For example, the preset resolution is 1920*1080, the preset width resolution is 1080, the preset height resolution is 1920, the image resolution of the to-be-processed image 1 is 4096*2160, the width image resolution is 2160, and the height image resolution is 4096. A ratio of the preset width resolution and the width image resolution is calculated to obtain a width scaling factor of 0.5 (1080 / 2160=0.5). A ratio of the height image resolution and the preset height resolution is calculated to obtain a height scaling factor of 0.47 (4096 / 1920=0.47). The height scaling factor (0.47) is determined as a target scaling factor. The to-be-processed image 1 is scaled according to the target scaling factor to obtain a corresponding scaled image. The resolution of the scaled image is 1925*1015 (1925=4096*0.47; 1015=2160*0.47).

[0073] Step S122: The corresponding to-be-fused image and the corresponding to-be-processed image are fused according to the image information to obtain the all-visual-effect image.

[0074] In some embodiments, the image information includes a to-be-blurred region. The first to-be-fused region and the corresponding second to-be-fused region are fused to obtain the all-visual-effect image. The first to-be-fused region is a to-be-blurred region of the to-be-fused image, and the second to-be-fused region is a to-be-blurred region of the to-be-processed image.

[0075] In some embodiments, the image information can include an image identifier. The image identifier of the to-be-fused image is the same as that of the corresponding to-be-processed image. The electronic device can determine the to-be-processed image corresponding to the to-be-fused image through the image identifier. For example, the to-be-processed image includes a to-be-processed image 1 and a to-be-processed image 2. The to-be-fused image 1 is an image obtained after processing the to-be-processed image 1. The image identifier of the to-be-fused image 1 is the same as that of the to-be-processed image 1, and the image identifier of the to-be-fused image 1 is not the same as that of the to-be-processed image 2.

[0076] It should be noted that the to-be-fused image is a to-be-processed image with a blur effect, the to-be-processed image does not have a blur effect, the image in the first to-be-fused region has a blur effect, the image in the second to-be-fused region does not have a blur effect, and the position of the first to-be-fused region in the to-be-fused image is the same as that of the corresponding second to-be-fused region in the to-be-processed image. That is, the image of the to-be-blurred region in the to-be-fused image with a blur effect is fused with the image of the to-be-blurred region in the corresponding to-be-processed image to obtain the image of the blurred region in the visual effect image, and then the visual effect image is obtained. The image of the blurred region in the visual effect image has a blur effect, the image of the visual effect image except the blurred region is the image of the to-be-processed image except the to-be-blurred region, and the image of the visual effect image except the blurred region does not have a blur effect.

[0077] For example, as shown in Figure 4 The first to-be-fused region includes to-be-blurred region A1 and to-be-blurred region B1 of the to-be-fused image 21, the images of the to-be-blurred region A1 and the to-be-blurred region B1 have a blur effect, the to-be-fused image 21 is an image obtained by performing a blur process on the to-be-processed image 22, the second to-be-fused region includes to-be-blurred region A2 and to-be-blurred region B2 of the to-be-processed image 22, the images of the to-be-blurred region A2 and the to-be-blurred region B2 have no blur effect, the image of the to-be-blurred region A1 is fused with the image of the to-be-blurred region A2 to obtain an image of a blurred region A3, the image of the to-be-blurred region B1 is fused with the image of the to-be-blurred region B2 to obtain an image of a blurred region B3, and a visual effect image 23 is obtained, the images of the blurred region A3 and the blurred region B3 in the visual effect image 23 have a blur effect, and the images other than the blurred region A3 and the blurred region B3 in the visual effect image 23 are images other than the to-be-blurred region A2 and the to-be-blurred region B2 in the to-be-processed image 22, and the images other than the blurred region A3 and the blurred region B3 in the visual effect image 23 have no blur effect.

[0078] The video processing method provided by the embodiment of the present application can maintain the visual effects of high-resolution images and low-resolution images at all times and can also reduce performance consumption in the Gaussian blur process.

Further, please refer to Figure 5 , which is a functional module diagram of a video processing apparatus provided by an embodiment of the present application.
