METHOD AND APPARATUS FOR PROVIDING COMPENSATION OFFSETS FOR A SET OF RESTORED IMAGE SAMPLES Russian patent published in 2019 - IPC H04N19/10 

FIELD: computer equipment.

SUBSTANCE: disclosed is a device for applying to an image of sample-adaptive offsets, wherein the apparatus comprises: means for obtaining, from a bit stream, position data relating to a band-type shift adaptive sample; wherein the obtained position data indicate the position of the range of chroma values, in which the selective adaptive offset selected from the full range of chroma values is to be applied, wherein said range is less than half the full range, and said range has a predetermined number of consecutive subranges, and each of said predetermined number of subranges includes a plurality of chroma values; apparatus for obtaining, from a bit stream, corresponding offset values for said successive subranges; apparatus for obtaining, from a bit stream, color sample values from image samples, which is decoded from a bit stream; and means for applying offset value for each said subrange to chroma sample values in corresponding subrange.

EFFECT: application of image adaptive to sample displacement.
