METHOD AND DEVICE FOR ENCODING VIDEO AND METHOD AND DEVICE FOR DECODING VIDEO THROUGH PIXEL VALUE COMPENSATION IN ACCORDANCE WITH PIXEL GROUPS Russian patent published in 2015 - IPC H04N19/85 H04N19/82 H04N19/463 

Abstract RU 2554555 C2

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to computer engineering. The method of decoding video comprises obtaining from a bit stream information on pixel value compensation in accordance with a pixel value band or a limiting value level, if information on pixel value compensation indicates a band, applying a compensation value of the predefined band obtained from the bit stream to the pixel included in the predefined band among pixels of the current block; and if information on pixel value compensation indicates a limiting value level, applying a compensation value of the predefined boundary direction obtained from the bit stream to the pixel in the predefined boundary direction among pixels of the current block, wherein the predefined band is one of bands formed by breaking down the full range of pixel values.

EFFECT: high quality of the reconstructed image.
