METHOD AND DEVICE FOR CODING/DECODING IMAGE SIGNALS Russian patent published in 2023 - IPC H04N19/109 H04N19/107 H04N19/119 H04N19/122 H04N19/132 H04N19/176 H04N19/503 H04N19/513 

FIELD: image encoding and decoding.

SUBSTANCE: list of merge candidates for the first block is generated. One of the merger candidates included in the list of merger candidates is selected. Motion compensation is performed for the first block based on the motion information of the selected fusion candidate, and the inter-site fusion candidate included in the inter-site motion information list is added to the fusion candidate list based on the number of spatial fusion candidates and temporal fusion candidates. merger included in the list of merger candidates. Based on the result of determining whether one inter-area fusion candidate included in the inter-area traffic information list is the same as at least one fusion candidate included in the fusion candidate list, it is determined whether or not to add one candidate. for a merger between sites in the list of candidates for merger. The determination is made by comparing at least one merge candidate whose index value is less than or equal to a threshold value with one inter-site merge candidate. Here, performing motion compensation for the first block includes performing motion compensation prediction for the first block using the plurality of fusion candidates.

EFFECT: increase in the efficiency of prediction carried out between images.
