METHOD OF DETERMINING POSITIONS OF REFERENCE SAMPLES WHEN ENCODING VIDEO Russian patent published in 2024 - IPC H04N19/70 H04N19/187 

Abstract RU 2824188 C2

FIELD: physics.

SUBSTANCE: invention relates to image processing. Such result is provided due to the fact that it is determined for conversion between the current video image and encoded representation of video, position of reference sample in reference image associated with current image, based on upper left position of image window. Image is at least said current image or said reference image, and the window is subject to processing in accordance with the processing rule during said transformation. Further, conversion is performed based on said determination.

EFFECT: high efficiency of encoding images.
