Method and Apparatus for Removing Redundancy in Motion Vector Predictors

摘要

A method for video coding a current block coded in an Inter, Merge, or Skip mode. The method determines neighboring blocks of the current block, wherein a motion vector predictor (MVP) candidate set is derived from MVP candidates associated with the neighboring blocks. The method determines at least one redundant MVP candidate, if said MVP candidate is within a same PU (Prediction Unit) as another MVP candidate in the MVP candidate set. The method removes said at least one redundant MVP candidate from the MVP candidate set, and provides a modified MVP candidate set for determining a final MVP, wherein the modified MVP candidate set corresponds to the MVP candidate set with said at least one redundant MVP candidate removed. Finally, the method encodes or decodes the current block according to the final MVP. A corresponding apparatus is also provided.

1. A video coding method for a current block coded in an Inter, Merge, or Skip mode, the method comprising:
determining neighboring blocks of the current block, wherein a motion vector predictor (MVP) candidate set is derived from MVP candidates associated with the neighboring blocks; determining at least one redundant MVP candidate, wherein an MVP candidate is determined to be said at least one redundant MVP candidate if said MVP candidate is within a same PU (Prediction Unit) as another MVP candidate in the MVP candidate set; removing said at least one redundant MVP candidate from the MVP candidate set; providing a modified MVP candidate set for determining a final MVP, wherein the modified MVP candidate set corresponds to the MVP candidate set with said at least one redundant MVP candidate removed; and encoding or decoding the current block according to the final MVP.
