METHOD AND DEVICE FOR INTER-FRAME PREDICTION BASED ON THE FUSION MODE Russian patent published in 2023 - IPC H04N19/52 

Abstract RU 2790325 C2

FIELD: imaging technology.

SUBSTANCE: invention relates to a method and device for inter-frame prediction. The result is achieved by compiling a list of candidates for the fusion of the current block, obtaining information about the movement of the current block from the list of candidates for the fusion and performing an inter-frame prediction of the current block using movement information, and the list of candidates for the fusion contains at least one of the spatial candidate for the fusion, a temporary candidate for the fusion or a combined candidate for the fusion, and a combined candidate for fusion is obtained by combining n candidates for fusion belonging to the list of candidates for fusion, moreover, information about the movement of a combined candidate for fusion is obtained by means of a weighted average of information about the movement of the first candidate for fusion and information about the movement of the second candidate for fusion.

EFFECT: increase in the accuracy of motion information by using not only a spatial/temporal fusion candidate, but also a combined fusion candidate.
