Title:
RESIDUAL CODING METHOD AND DEVICE, VIDEO CODING METHOD AND DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/217610
Kind Code:
A1
Abstract:
The present disclosure provides a residual coding method. The method comprises: when the current frame is an inter-frame prediction frame, determining whether a residual of a background region in the current frame needs to be compensated for; and when the residual of the background region in the current frame needs to be compensated for, coding first residual data, and when the residual of the background region in the current frame does not need to be compensated for, coding second residual data, wherein the first residual data is residual data of an entire image of the current frame, and the second residual data is residual data of a target region in the current frame. In the present disclosure, a residual of a background region in each inter-frame prediction frame is selectively compensated for, such that the coding efficiency can be improved. The present disclosure further provides a video coding method using the residual coding method, and corresponding devices and a storage medium.
