METHOD AND APPARATUS OF MOTION AND DISPARITY VECTOR PREDICTION AND COMPENSATION FOR 3D VIDEO CODING

摘要

A method and apparatus for deriving MV/MVP (motion vector or motion vector predictor) or DV/DVP (disparity vector or disparity vector predictor) associated Skip mode, Merge mode or Inter mode for a block of a current picture in three-dimensional (3D) video coding are disclosed. The 3D video coding may use temporal prediction and inter-view prediction to exploit temporal and inter-view correlation. MV/DV prediction is applied to reduce bitrate associated with MV/DV coding. The MV/MVP or DV/DVP for a block is derived from spatial candidates, temporal candidates and inter-view candidates. For the inter-view candidate, the position of the inter-view co-located block can be located using a global disparity vector (GDV) or warping the current block onto the co-located picture according to the depth information. The candidate can also be derived as the vector corresponding to warping the current block onto the co-located picture according to the depth information.
