DISPARITY VECTOR REFINEMENT IN VIDEO CODING

摘要

A video coding device performs a disparity vector derivation process for a current block of multi-view video data. The current block is in a current view. An availability value indicates that a disparity vector for the current block is unavailable when the disparity vector derivation process is unable to derive the disparity vector for the current block. When the availability value indicates that the disparity vector derivation process has not derived the disparity vector for the current block, the video coding device generates a disparity vector for the current block in another manner.

1. A method for decoding multi-view video data, the method comprising:
performing a disparity vector derivation process for a current block of the multi-view video data, the current block being in a current view; setting an availability value such that the availability value indicates that a disparity vector for the current block is unavailable when the disparity vector derivation process is unable to derive the disparity vector for the current block; when the availability value indicates that the disparity vector for the current block is unavailable, generating a refined disparity vector for the current block by performing a disparity vector refinement process that accesses a depth view component of a reference view; and decoding the current block based on the refined disparity vector for the current block.
