Abstract

The invention provides a video image prediction method and device, and provides a mode for determining the maximum length of a candidate motion vector list of a sub-block fusion mode. The method comprises the following steps: analyzing a first identifier from a code stream; and when the first identifier indicates that a candidate mode adopted by a to-be-processed block for inter-frame prediction comprises an affine mode, analyzing a second identifier from the code stream, the second identifier being used for indicating the maximum length of a first candidate motion vector list, the first candidate motion vector list being a candidate motion vector list constructed when the to-be-processed block adopts a sub-block fusion prediction mode; and determining the maximum length of the first candidate motion vector list according to the second identifier.

Description

[0001] This application claims the priority of a Chinese patent application filed with the China Patent Office on October 29, 2018, with application number 201811268188.2, and the title of the invention is "A Method and Device for Inter-frame Prediction", the entire contents of which are incorporated herein by reference Applying. technical field [0002] The present application relates to the technical field of image coding and decoding, and in particular to a video image prediction method and device. Background technique [0003] With the development of information technology, high-definition television, web conferencing, IPTV, 3D television and other video services are developing rapidly, and video signals have become the most important way for people to obtain information in their daily lives due to their advantages of intuition and efficiency. Because the video signal contains a large amount of data, it needs to occupy a large amount of transmission bandwidth and storage...
