METHOD AND DEVICE FOR ENCODING/DECODING IMAGE SIGNALS Russian patent published in 2024 - IPC H04N19/593 H04N19/105 H04N19/119 

FIELD: physics.

SUBSTANCE: invention relates to video encoding and decoding means. Line of reference readings of the current block is determined. It is determined whether a candidate intra prediction mode exists, which is the same as the intra prediction mode of the current block. Internal prediction mode of the current block is obtained based on the determination. Internal prediction is performed with respect to the current block based on the reference sample line and the internal prediction mode. Method further includes a step of determining whether or not the current block should be split into a plurality of sub-blocks. When a current block is divided into a plurality of sub-blocks, the plurality of sub-blocks share a single intra prediction mode. Type of transformation in the horizontal direction of the sub-block of the current block is determined based on the width of the sub-block, and the type of transformation in the vertical direction of the sub-block is determined based on the height of the sub-block.

EFFECT: high efficiency of video encoding.
