Problems solved by technology

The video picture processed by FRUC usually has certain defects, which may not be obvious when the video is played continuously, but these defects are especially prominent when the video is paused or played at a slow speed
For example, in the scene of an exemplary embodiment of the image processing method of the present disclosure, the image to be processed contains a video image of a fast-moving small object, for example, a picture of a fast-moving football in a football match video, in the video When the frame rate is low, after using FRUC to process this type of video image, it may cause the problem that some processed pixels of the video screen have a large deviation from the original pixel value.

Abstract

The present disclosure relates to an image processing method, device and storage medium, wherein the image processing method includes: judging the first pixel value of the first pixel point in the first image frame and the second pixel value of the second pixel point in the second image frame Whether the difference between the values ​​is greater than a threshold, the first image frame is generated based on the third image frame and the fourth image frame using an interpolation method, and the second image frame is generated based on the third image frame and the fourth image frame using an extrapolation method The fourth image frame is generated, wherein the position of the first pixel is the same as that of the second pixel; when the difference is greater than the threshold, according to the first pixel value and the second pixel value to obtain a third pixel value, and use the third pixel value as the pixel value of the first pixel point to obtain the processed first image frame. The present disclosure improves the video image quality while increasing the frame rate.

Description

technical field [0001] The present disclosure relates to the field of image processing, and in particular, to an image processing method, device and storage medium. Background technique [0002] At present, the frame rate of video on the Internet is generally 24 frames, 25 frames or 30 frames per second. Although this type of video can meet the requirements of the human eye for visual persistence and smooth playback of the picture, it is difficult for users to watch some special videos. Or when the user has higher requirements for viewing experience, it is necessary to provide a video with a higher frame rate. In order to obtain a video with a higher frame rate, you can directly shoot a video with 50 frames per second, 60 frames per second or even 120 frames per second when shooting a video, but for a video with a low frame rate that has been shot, you need to use FRUC (Frame Rate Up Conversion) algorithm to increase the frame rate of the video. Video images processed by F...
