METHOD AND APPARATUS FOR IMPLEMENTING INTRAFRAME PREDICTION Russian patent published in 2016 - IPC H04N19/105 H04N19/593 

FIELD: physics.

SUBSTANCE: intraframe prediction method is disclosed. The method includes a step of determining reference pixels based on pixels adjacent to the current block. Further, the method comprises obtaining a predicted pixel of the current block by performing intraframe prediction in the current block based on the reference pixels. The determination of reference pixels includes replacing an unavailable pixel contained in adjacent pixels using an available pixel adjacent to the unavailable pixel from among pixels adjacent to the current block.

EFFECT: high efficiency of intraframe prediction owing to that said prediction is performed based on variation of reference pixel values of adjacent blocks.
