Method and Apparatus of Inter-View Candidate Derivation in 3D Video Coding

摘要

A method and apparatus for three-dimensional video coding are disclosed. Embodiments according to the present invention apply the pruning process to one or more spatial candidates and at least one of the inter-view candidate and the temporal candidate to generate a retained candidate set. The pruning process removes any redundant candidate among one or more spatial candidates and at least one of the inter-view candidate and the temporal candidate. A Merge/Skip candidate list is then generated, which includes the retained candidate set. In one embodiment, the temporal candidate is exempted from the pruning process. In another embodiment, the inter-view candidate is exempted from the pruning process. In other embodiments of the present invention, the pruning process is applied to the inter-view candidate and two or more spatial candidates. The pruning process compares the spatial candidates with the inter-view candidate.

1. A method for a three-dimensional video encoding or decoding system, the method comprising:
receiving to-be-processed data associated with a current block; determining spatial candidates associated with spatial neighboring blocks of the current block, and an inter-view candidate and a temporal candidate for the current block, wherein one candidate corresponds to one motion vector candidate or one disparity vector candidate; applying pruning process to one or more spatial candidates and at least one of the inter-view candidate and the temporal candidate to generate a retained candidate set; wherein the pruning process removes any redundant candidate among said one or more spatial candidates and said at least one of the inter-view candidate and the temporal candidate; generating a Merge/Skip candidate list comprising the retained candidate set; and applying inter-view predictive encoding or decoding to the to-be-processed data using the Merge/Skip candidate list when the to-be-processed data is coded or decoded in Merge/Skip mode.
