METHOD OF ENCODING IMAGES Russian patent published in 2024 - IPC H04N19/70 H04N19/13 H04N19/91 

FIELD: images encoding means.

SUBSTANCE: method of coding a sample adaptive offset (SAO) value using arithmetic coding into a bitstream includes the following steps. Determining the SAO type parameter for the SAO value, wherein the SAO type parameter indicates whether the SAO value is a boundary offset value or a range offset value. SAO value is to be added to the pixel value of the reconstructed image. Total number of consecutive "1" is determined, wherein the total number of consecutive "1" represents the value of the SAO value. SAO type parameter and total number of consecutive "1" are encoded into a bit stream using arithmetic coding with constant probability.

EFFECT: high efficiency of encoding images.
