Title:
METHOD, APPARATUS, AND MEDIUM FOR VIDEO PROCESSING
Document Type and Number:
WIPO Patent Application WO/2023/072216
Kind Code:
A1
Abstract:
Embodiments of the present disclosure provide a solution for video processing. A method for video processing is proposed. The method comprises: determining, during a conversion between a target video block of a video and a bitstream of the video, a first prediction of the target video block by using an inter prediction tool; determining a second prediction by performing a motion compensation process on the first prediction; obtaining a third prediction by performing a forward mapping process on the second prediction; and performing the conversion based on the third prediction. In this way, the prediction of the target video block can be improved by applying the motion compensation process, and thus the coding effectiveness and coding efficiency can be improved.
