Method and Apparatus for Derivation of Motion Vector Candidate and Motion Vector Prediction Candidate

摘要

A method for deriving a motion vector predictor (MVP) receives motion vectors (MVs) associated with reference blocks of the current block. The method determines at least one first spatial search MV associated with a first MV searching order and at least one second spatial search MV associated with a second MV searching order for each neighboring reference block. Then, the method determines whether a first available-first spatial search MV exists for said at least one neighboring reference block according to the first MV searching order, and provides the first available-first spatial search MV as a spatial MVP for the current block. Finally, the method determines whether a first available-second spatial search MV exists for said at least one neighboring reference block according to the second MV searching order only if none of first spatial search MVs for said at least one neighboring reference block is available.

1. A method for deriving a motion vector predictor (MVP) for a motion vector (MV) of a current block in Inter, or Merge, or Skip mode, the method being executed by a processor and comprising:
receiving motion vectors (MVs) associated with reference blocks of the current block, wherein the reference blocks comprise at least one neighboring reference block of the current blocks; determining at least one first spatial search MV associated with a first MV searching order and at least one second spatial search MV associated with a second MV searching order for each neighboring reference block; determining whether a first available-first spatial search MV exists for said at least one neighboring reference block according to the first MV searching order, and when the first available-first spatial search MV exists for said at least one neighboring reference block, providing the first available-first spatial search MV as a spatial MVP for the current block; and determining whether a first available-second spatial search MV exists for said at least one neighboring reference block according to the second MV searching order only if none of first spatial search MVs for said at least one neighboring reference block is available; wherein a process of redundancy check is performed after the spatial MVP and at least another MVP are derived.
