ENCODER, DECODER AND CORRESPONDING METHODS FOR REDUCING COMPLEXITY IN INTRAFRAME PREDICTION FOR PLANAR MODE Russian patent published in 2024 - IPC H04N19/17 

Abstract RU 2820991 C1

FIELD: physics.

SUBSTANCE: invention relates to image processing. For this purpose, a method of encoding is disclosed. This method comprises the following steps: obtaining the height and width of the current block without using a truncation operation; calculating the value of the vertical component of the prediction by the intraframe method based on the height and width of the prediction unit; calculating the value of the horizontal component of the predicted intraframe counting method based on the height and width of said block; and generating the count predicted by the intraframe method based on the value of the vertical component and the value of the horizontal component.

EFFECT: simplification of prediction using planar mode and high efficiency of coding and decoding due to processing of vertical and horizontal components.
