IMAGE OR VIDEO ENCODING BASED ON ACT RESIDUE Russian patent published in 2023 - IPC H04N19/60 

FIELD: video encoding.

SUBSTANCE: invention is related to a technology for encoding images or video based on the adaptive colour transform (ACT) residue. The residual sample can be derived by applying an adaptive colour transform (ACT) to the current block based on information associated with the ACT, wherein the residual sample is derived by constraint based on the constraint boundary, and the constraint boundary is determined based on bit depth.

EFFECT: increasing image/video encoding efficiency.
