Abstract

The invention discloses a method for determining an intra-frame prediction mode, electronic equipment, a system, and a storage medium. The method includes: acquiring angle information corresponding to each intra-frame prediction mode in all intra-frame prediction modes; The angle information corresponding to the mode is normalized to obtain the target angle information corresponding to each intra prediction mode; determine the target macroblock in the intra prediction area; calculate the target gradient of the target macroblock; calculate the target gradient The target difference with each target angle information; according to the target difference, determine M undetermined intra prediction modes from all the intra prediction modes; use the M undetermined intra prediction modes for prediction, and obtain M cost values; according to the M cost values, determining the target intra prediction mode of the target macroblock from the M undetermined intra prediction modes can quickly determine the target intra prediction mode and improve prediction efficiency.

Description

technical field [0001] The present invention relates to the field of intra-frame prediction, in particular to a method for determining an intra-frame prediction mode, an electronic device, a system and a storage medium. Background technique [0002] Intra prediction is one of the core technologies of the H.264 video coding standard. It refers to using the correlation of the video space domain to predict the current pixel using the encoded pixels of the current image, so as to achieve the purpose of removing video space redundancy. There are up to 9 intra-frame 4x4 prediction modes for each macroblock (Macro Block, MB) of H.264, including DC mode and 8 angle-related modes. Therefore, during the H.264 encoding process, it is usually necessary to traverse the nine intra-frame prediction modes, which requires a relatively large amount of calculation. Contents of the invention [0003] The main purpose of the present invention is to provide a method for determining an intra pr...
