AI Technical Summary

Technical Problem

The existing video coding and decoding technology has problems with low efficiency and insufficient accuracy in the distortion calculation method in the adaptive reordering of the merge candidate list, which affects the video coding and decoding performance.

Method used

By improving the adaptive reordering method of the merge candidate list based on template matching, the template size is determined and template matching is used to adaptively reorder multiple candidates in the merge candidate list. The optimal candidate is selected in combination with rate-distortion optimization, thereby improving the sorting accuracy of the merge candidate list.

Benefits of technology

Improved video encoding and decoding efficiency and accuracy, especially the sorting effect in different content scenarios, and improved video encoding and decoding performance.

Abstract

The invention provides a method and a device for video coding and decoding. A video encoding method may include: acquiring a merge candidate list of a current block; determining a template size for performing adaptive reordering (ARMC) of the merge candidate list based on template matching; on the basis of the template size, matching a plurality of candidates in the merge candidate list by using a template to carry out self-adaptive reordering; selecting an optimal candidate from the merge candidate list after adaptive reordering based on rate distortion optimization; an index indicating the optimal candidate is signaled in the bitstream.
