METHOD AND DEVICE FOR ENCODING/DECODING IMAGE SIGNALS Russian patent published in 2024 - IPC H04N19/513 H04N19/176 

FIELD: video encoding.

SUBSTANCE: list of merge candidates for the current block is generated. One of the merger candidates included in the list of merger candidates is selected. The first affine source vector and the second affine source vector of the current block are obtained based on the first affine source vector and the second affine source vector of the specified merge candidate. An affine vector is obtained for a subblock in the current block by using the first affine source vector and the second affine source vector of the current block, where the subblock is a region with a size that is smaller than the size of the current block. The first affine source vector and the second affine merge candidate source vectors are obtained based on the motion information of a neighboring block adjacent to the current block. When a neighboring block is included in a code tree element different from the current block's code tree element, the first affine source vector and the second affine merge candidate source vectors are obtained based on the motion vectors of the bottom left subblock and bottom right subblock of the neighboring block.

EFFECT: increased efficiency of video coding.
