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 partitions are disclosed. A current texture block (to be encoded or decoded) comprises multiple partition blocks 510. A corresponding depth block in a known reference view is located 520 using a derived disparity vector (DV). The method derives 530 a single partition decision using consideration of depth block samples from the reference view and splits 540 each partition block of the texture block into sub-blocks according to the partition decision. The partition blocks may be split into sub-blocks vertically or horizontally depending upon the outcome of the depth sample testing. Once partitioning is complete, VSP processing is applied (550-590) to derive inter-view encoding or decoding parameters for each sub-block in the current texture block.
