METHOD FOR IMAGE DECODING, METHOD FOR IMAGE ENCODING AND MACHINE-READABLE INFORMATION CARRIER Russian patent published in 2022 - IPC H04N19/105 H04N19/53 H04N19/597 

FIELD: image encoding/decoding.

SUBSTANCE: group of inventions relates to technologies of encoding/decoding of three-dimensional images. A method for image decoding is proposed. The method contains a stage of determination of movement information related to a current block. Next, according to the method, an elementary value of prediction for the current block is determined based on movement information related to the current block. Moreover, the stage of determination of movement information related to the current block includes: determination of whether a central subblock corresponding to a central position of the current block has movement information in a reference block.

EFFECT: increase in the efficiency of image encoding/decoding by means of elimination of dependence on data, when determining movement information.
