METHOD AND DEVICE FOR INTRAFRAME PREDICTION Russian patent published in 2024 - IPC H04N19/105 H04N19/593 H04N19/157 

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 of internal prediction. Disclosed is an intraframe prediction device configured to obtain an intraframe prediction mode of the current block, determining, among a plurality of pixel lines, a pixel line for intraframe prediction of the current block and performing intraframe prediction of current block based on intraframe prediction mode and pixel line, wherein obtaining includes: obtaining an internal prediction mode based on a predetermined default mode or a group of most probable modes (MPM) candidates. 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 intraframe prediction accuracy can be improved.

EFFECT: high efficiency of compressing images.
