Title:
PREDICTION REFINEMENT FOR COMBINED INTER INTRA PREDICTION MODE
Document Type and Number:
WIPO Patent Application WO/2020/103872
Kind Code:
A1
Abstract:
A method for processing a video includes performing a conversion between a current block of visual media data and a corresponding coded representation of the visual media data, wherein the conversion of the current block includes determining whether a use of one or both of a bi-directional optical flow (BIO) technique or a decoder-side motion vector refinement (DMVR) technique to the current block is enabled or disabled, and wherein the determining the use of the BIO technique or the DMVR technique is based on a cost criterion associated with the current block.
