METHOD AND SYSTEM FOR MOTION REFINEMENT IN VIDEO CODING

Abstract:

The present disclosure provides systems and methods for motion refinement in video coding. The method can include: receiving a bitstream comprising a target image block; and enabling or disabling decoder side motion vector refinement (DMVR) for the target image block, wherein the enabling or disabling is based on at least one of: a flag signaled in the bitstream, or whether the DMVR is enabled or disabled for a neighboring block of the target image block.
