Method of View Synthesis Prediction in 3D Video Coding

摘要

A method and apparatus for three-dimensional or multi-view video encoding and decoding using VSP (view synthesis prediction) with uniform sub-block partition are disclosed. For a current texture block comprising multiple partition blocks, the system derives a single partition decision and partitions each partition block of the current texture block into multiples sub-blocks according to the single partition decision. The VSP processing is then applied to each sub-block to derive the inter-view prediction using VSP. The single partition decision is derived using depth samples of the depth block in a reference view.

1. A method for three-dimensional or multi-view video encoding or decoding using VSP (view synthesis prediction), the method comprising:
receiving input data associated with a current texture block in a dependent view, wherein the current texture block comprises multiple partition blocks; locating a depth block in a reference view corresponding to the current texture block using a derived DV (disparity vectors); deriving a single partition decision for the current texture block using the depth block; partitioning each partition block of the current texture block into multiples sub-blocks according to the single partition decision; and for each sub-block,
determining a corresponding DV based on the depth block;locating prediction data in the reference view using the corresponding DV; andapplying inter-view encoding or decoding to said each sub-block using the prediction data.
