METHOD FOR DECODING VIDEOS AND IMAGES USING BLOCK SEGMENTATION Russian patent published in 2023 - IPC H04N19/119 H04N19/176 H04N19/70 

FIELD: video and image decoding.

SUBSTANCE: result is achieved by the decoder segmenting the encoded signal into a plurality of blocks using a set of block segmentation modes obtained by combining one or more block segmentation modes, each of which specifies a type of segmentation, after which the decoder decodes the plurality of blocks, the plurality of modes of block segmentation includes a first segmentation mode that specifies a segmentation direction and a total number of segments for segmenting a first block, and a second block segmentation mode that specifies a segmentation direction and a total number of segments for segmentation of a second block that is one of the blocks, obtained after the first block is segmented in segmentation, when the total number of segments of the first block segmentation mode is three, the second block is the centre block from among the blocks obtained after the first block is segmented, and the segmentation direction for the second segmentation mode is identical to the segmentation direction for the first block segmentation mode, wherein the second block segmentation mode includes only the block segmentation mode indicating that the total number of segments is three, and wherein the parameter for identifying the second block segmentation mode includes a first flag that indicates whether the block is to be segmented horizontally or vertically, and does not include a second flag that indicates the total number of segments into which the block is to be segmented.

EFFECT: increasing the efficiency of video compression.
