NONLINEAR ADAPTIVE CONTOUR FILTERING IN VIDEO DATA PROCESSING Russian patent published in 2024 - IPC H04N19/80 

Abstract RU 2812618 C2

FIELD: video data processing technologies.

SUBSTANCE: encoding the video block of video as an encoded video block; generating reconstruction samples from the encoded video block; performing a constraint operation on the reconstruction samples, wherein the constraint parameter used in the constraint operation is a function of the constraint index and the bit depth of the reconstruction samples or the bit depth of the video block samples; applying a nonlinear adaptive contour filter to the output result of the constraint operation and generating an encoded video representation using the encoded video block.

EFFECT: increase of efficiency of video encoding.
