Problems solved by technology

Problems existing in the prior art (1) Transmitting the syntax element of GEOIdx requires too many extra bits, which seriously affects the performance of GEO
If there are 128 modes, it is necessary to write the value from 0 to 127 into the code stream, and it needs to consume 7 bits to represent
(2) For all CUs, all possible GEO partition modes are tried on the encoding side, and the complexity is high

Abstract

The invention discloses a geometric division mode prediction method and device based on coding and decoding terminals, a storage medium and a terminal. The method comprises the steps: carrying out theoptimal mode prediction of a current coding block, and selecting a most possible mode set from a total mode set; performing mode decision in the most possible mode set; and writing the index of the optimal mode obtained by final decision in the most possible mode set into a code stream; performing mode decision from the total mode set, identifying whether the optimal mode obtained by final decision is in the most possible mode set or not by using an identification bit, if so, writing the index of the optimal mode in the most possible mode set into the code stream, and otherwise, writing the index of the optimal mode in the total mode set into the code stream. Therefore, according to the embodiment of the invention, the division mode coding cost can be reduced, the compression performanceis improved, and the coding end complexity is reduced.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method, device, storage medium and terminal for predicting a geometric partition mode based on a codec terminal. Background technique [0002] Video coding mainly includes intra-frame prediction, inter-frame prediction, transformation, quantization, entropy coding, and loop filtering. The inter-frame prediction technology utilizes the time-domain correlation between adjacent video frames, uses the previously coded reconstructed frame as a reference frame, and predicts the current frame (the frame currently being coded) through motion estimation and motion compensation. In this way, the time redundant information of the video is removed. For a frame of image, the entire frame of image will not be processed directly during the encoding process, and it needs to be divided into a large coding area (Coding Tree Unit, CTU), such as 64x64, 128x128 in size. Each CTU can be ...
