Abstract

The invention relates to a motion compensation method and device, computer equipment and a storage medium, belongs to the technical field of image processing. The method comprises the steps: featuresof a to-be-processed image block are input into a first target model; the first target model performs virtual segmentation on the to-be-processed image block, output any sub-block of which the size isgreater than a preset size, segments the to-be-processed image block according to the size of any sub-block. Due to the fact that the size of the target sub-blocks obtained after segmentation is larger than the preset size, the number of the target sub-blocks segmented from the to-be-processed image block is controllable, when the number of the target sub-blocks is small, the number of times of motion compensation conducted by the encoding and decoding end is small, the number of times of memory reading is small, and then consumption of memory bandwidth can be reduced.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular to a motion compensation method, device, computer equipment and storage medium. Background technique [0002] With the maturity of computer technology, video coding and decoding technology has also developed greatly. When performing video coding and decoding on an image frame, first, the coding and decoding end needs to sample any image to obtain a brightness block and two color blocks. secondly, the codec end splits each luma block and chrominance block to obtain multiple luma sub-blocks and multiple chroma sub-blocks; again, the codec end obtains the motion vector and sum of each luma sub-block The motion vector of each chroma sub-block; finally, the codec performs motion compensation for each luma sub-block according to the motion vector of each luma sub-block, and performs motion compensation for each chroma sub-block according to the motion vector of each ...
