Abstract

The invention provides a block division method, an inter-frame prediction method, a video coding method and a related device. The inter-frame prediction method comprises the following steps: determining a weight matrix of a current block based on an inter-frame angle weighting prediction mode; and determining a first rectangular sub-block and a second rectangular sub-block of the current block by using the weight matrix, and performing motion compensation on the first rectangular sub-block and the second rectangular sub-block by using different motion information to obtain a predicted value of the first rectangular sub-block and a predicted value of the second rectangular sub-block. According to the invention, the inter-frame prediction efficiency can be improved.

Description

technical field [0001] The present application relates to the technical field of inter-frame prediction, in particular to a block division method, an inter-frame prediction method, a video encoding method and related devices. Background technique [0002] Due to the relatively large amount of video image data, it is usually necessary to encode and compress it. The compressed data is called a video code stream. The video code stream is transmitted to the client through a wired or wireless network, and then decoded and viewed. [0003] The entire video coding process includes prediction, transformation, quantization, entropy coding and other processes. The prediction is divided into two parts: intra prediction and inter prediction. Inter-frame prediction uses the temporal correlation between image frames to compress the image. During the long-term research and development process, the inventors of the present application found that the current inter-frame prediction method s...
