Title:
ENCODING AND DECODING METHOD AND APPARATUS FOR MOTION INFORMATION
Document Type and Number:
WIPO Patent Application WO/2019/052330
Kind Code:
A1
Abstract:
Provided are an encoding and decoding method and apparatus for predicted motion information about an image block. The decoding method comprises: parsing a code stream to obtain target identification information about target predicted motion information about an image block to be processed; determining N pieces of candidate predicted motion information, the N pieces of candidate predicted motion information comprising the target predicted motion information, where N is an integer greater than 1; acquiring a distortion value corresponding to each of the N pieces of candidate predicted motion information, the distortion value being determined by a reconstructed image block adjacent to a reference image block indicated by the candidate predicted motion information and a reconstructed image block adjacent to the image block to be processed; according to magnitude relationships of the acquired N distortion values, determining first identification information about each of the N pieces of candidate predicted motion information, the N pieces of candidate predicted motion information corresponding to respective pieces of first identification information on a one-to-one basis; and determining candidate predicted motion information corresponding to first identification information matching the target identification information to be the target predicted motion information.
