METHOD, EQUIPMENT AND DEVICES FOR ENCODING AND DECODING Russian patent published in 2024 - IPC H04N19/117 

FIELD: video encoding and decoding technologies.

SUBSTANCE: result is achieved by the fact that if the current pixel point in the current block satisfies the condition for enabling the extended refinement mode, determining the gradient value of the current pixel point based on the initial pixel value of the current pixel point and the initial pixel value of the surrounding pixel point of the current pixel point; based on the gradient value of the current pixel point and the initial pixel value of the current pixel point, a specified pixel value of the current pixel point is determined.

EFFECT: high efficiency of encoding video images.
