METHOD AND DEVICE FOR INTRA-FRAME PREDICTION Russian patent published in 2023 - IPC H04N19/105 H04N19/593 H04N19/157 

FIELD: image encoding and decoding technology.

SUBSTANCE: invention is related in particular to a method and apparatus for encoding/decoding intra prediction. A device for intra-frame prediction is proposed, which is capable of obtaining the intra-frame prediction mode of the current block, determining among the plurality of pixel lines a pixel line for intra-frame prediction of the current block, and performing intra-frame prediction of the current block based on the intra-frame 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 intra-frame prediction accuracy can be improved.

EFFECT: increase of efficiency of image compression.
