METHOD, APPARATUS, AND MEDIUM FOR VIDEO PROCESSING

WIPO Patent Application WO/2023/078449

A1

Embodiments of the present disclosure provide a solution for video processing. A method for video processing is proposed. The method comprises: deriving, during a conversion between a target block of a video and a bitstream of the target block, a sample-based optical flow with an affine motion model for each sub-block associated with the target block; and performing the conversion based on the sample-based optical flow.
