METHOD FOR IMAGE ENCODING BASED ON INTERNAL PREDICTION USING MPM-LIST AND EQUIPMENT FOR IT Russian patent published in 2024 - IPC H04N19/11 H04N19/105 H04N19/593 H04N19/70 H04N19/176 H04N19/159 

FIELD: image encoding.

SUBSTANCE: MPM flag information, planar flag information and MPM index information are generated. MPM flag information is related to whether to derive the intra prediction mode for the current unit on the most likely mode (MPM) candidates for the current unit. Planar flag information is related to whether to determine the intra prediction mode for the current unit as the planar mode. The MPM index information is associated with one of 5 possible non-planar MPM options from the possible MPM options for the current block. Image information containing MPM flag information, planar flag information and MPM index information are encoded. The MPM flag information is configured in the coding unit syntax for the current block. Based on the value of the MPM flag information representing that the intra prediction mode for the current block is retrieved based on the MPM candidates, the planar flag information is configured in the coding unit syntax.

EFFECT: improved efficiency of image encoding.
