METHOD AND DEVICE FOR INTRAFRAME PREDICTION Russian patent published in 2024 - IPC H04N19/117 H04N19/105 H04N19/593 H04N19/82 

FIELD: image encoding and decoding.

SUBSTANCE: invention relates to the technology of encoding and decoding an image and in particular to a method and device for encoding/decoding internal prediction. Disclosed is an intraframe prediction device configured to obtain an intraframe prediction mode of the current block, determining, among the plurality of pixel lines, a pixel line for intraframe prediction of the current block and performing intraframe prediction of the current block based on the intraframe prediction mode and the pixel line. In addition, the first reference pixel of the determined pixel line can be selectively filtered, and the prediction pixel of the current block can be selectively corrected, and thus the accuracy of intraframe prediction can be improved. Additionally, reference pixels are interpolated using a predetermined interpolation filter or one of a plurality of candidate interpolation filter groups.

EFFECT: high efficiency of compressing images.
