Video encoding and decoding method and device

Abstract

A video encoding and decoding, method and device are provided, the method comprising: obtaining a reconstructed image, the reconstructed image comprising a first encoding unit and a second encoding unit, the first encoding unit comprising a first image block, the second encoding unit comprising a second image block, the first image block and the second image block being adjacent blocks; and if thefirst coding unit adopts a geometric division prediction mode and the first image block is located on a division boundary line based on the geometric division prediction mode, performing deblocking filtering on the first image block and the second image block. According to the video coding and decoding method provided by the embodiment of the invention, if one image block of two adjacent image blocks in the reconstructed image adopts a geometric division prediction mode and the image block is located on the division boundary line of the coding unit of the image block, by performing deblockingfiltering on the adjacent image block, the blocking effect between the adjacent image blocks can be avoided as much as possible, and the subjective and objective quality of the compressed video can be further improved.

AI Technical Summary

Problems solved by technology

At present, regarding the deblocking filter technology, there may be block effects between adjacent image blocks without deblocking filtering for the image block, or there may be no block effect between adjacent image blocks and the adjacent image blocks are deblocked Block filtering, resulting in reduced quality of compressed video
