Abstract

The invention discloses a video processing method and device, electronic equipment and a storage medium, and the method comprises the steps: carrying out the preset partitioning processing of a first image frame and a second image frame in a to-be-processed video, and obtaining a target number of first pixel blocks and a target number of second pixel blocks; obtaining a first target pixel block existing in the target number of second pixel blocks, wherein a plurality of second target pixel blocks matched with the first target pixel block exist in the first pixel block; obtaining a motion vector of the first target pixel block relative to each second target pixel block to obtain a plurality of first motion vectors; based on the weight corresponding to each second target pixel block, performing weighted calculation on the plurality of first motion vectors to obtain a motion vector corresponding to the first target pixel block, the weight corresponding to a specified pixel block in the plurality of second target pixel blocks being greater than the weights corresponding to other pixel blocks; and performing frame insertion processing based on the motion vector corresponding to the first target pixel block. According to the method, the frame insertion accuracy can be improved.

Description

technical field [0001] The present application relates to the technical field of video processing, and more specifically, to a video processing method, device, electronic equipment, and storage medium. Background technique [0002] With the rapid advancement of technology and living standards, electronic devices (such as smart phones, tablet computers, etc.) have become one of the electronic products commonly used in people's lives. When people play video through electronic devices, in order to improve the smoothness of video playback, frame insertion processing is performed on the played video. However, in the related art, when there are multiple repetitive objects in the video, the accuracy of the motion estimation is insufficient, thus resulting in poor frame interpolation effect. Contents of the invention [0003] In view of the above problems, the present application proposes a video processing method, device, electronic equipment and storage medium. [0004] In the...
