IMPROVED CODING WITH INTRA-FRAME PREDICTION USING PLANAR REPRESENTATIONS Russian patent published in 2018 - IPC H04N19/593 H04N19/91 G06T9/00 

FIELD: data processing.

SUBSTANCE: invention relates to the field of video encoding. In the invention, the first prediction value is calculated using linear interpolation between the value of the corresponding pixels of the horizontal border and the value of one of the pixels of the vertical border and the second prediction value is calculated using linear interpolation between the value of the corresponding pixels of the vertical border and the value of one of the pixels of the horizontal border. Above first and second prediction values are then averaged to obtain the corresponding pixel prediction value in the prediction block. And the difference between the prediction block and the target block is reported to the decoder.

EFFECT: technical result is an increase in coding efficiency with intraframe prediction.
