METHOD AND DEVICE FOR IMAGE PREDICTION AND COMPUTER READABLE DATA MEDIUM Russian patent published in 2023 - IPC H04N19/103 

FIELD: video encoding technologies.

SUBSTANCE: invention relates to a method and device for image prediction. The technical result is to increase the efficiency of video coding by reducing redundancy in the image prediction process. The result is achieved in that the image prediction method includes: determining whether a merge mode is used for the current image block; when the merge mode is used for the current image block, determining whether the level-1 merge mode is available for the current image block; if the first merge mode is not available, and the high-level syntax element corresponding to the first merge mode indicates that the first merge mode is prohibited from being used, directly defining the second merge mode as the target merge mode applicable to the current image block, wherein both the first merge mode and the second merge mode belong to the level-2 merge mode; and predicting the current image block based on the target fusion mode.

EFFECT: increased efficiency of video coding by reducing redundancy in the image prediction process.
