METHOD AND DEVICE FOR EFFECTIVE ENCODING OF RESIDUAL BLOCKS Russian patent published in 2023 - IPC H04N19/119 H04N19/86 H04N19/117 

FIELD: image coding.

SUBSTANCE: method for decoding video images and a device for decoding video images. In order to efficiently encode the residual blocks obtained from the block-based motion compensation, the video encoder and the video decoder divide the corresponding residual block of the current block into two sub-blocks in the horizontal or vertical direction, and encode only one residual sub-block of the two residual sub-blocks, where the filtering block is made with the ability to set a grid of N samples at equal intervals in the horizontal and vertical directions and perform deblocking filtering on the boundary between two sub-blocks in the current block, which coincides with the grid boundary. The current block is a brightness block, a horizontal transform kernel and a vertical transform kernel for said one sub-block are determined based on the relative position of one sub-block in the current block.

EFFECT: increasing the efficiency of encoding/decoding of the residual blocks.
