Method and Apparatus of View Synthesis Prediction in 3D Video Coding

摘要

A method and apparatus for a three-dimensional encoding or decoding system incorporating view synthesis prediction (VSP) with reduced computational complexity and/or memory access bandwidth are disclosed. The system applies the VSP process to the texture data only and applies non-VSP process to the depth data. Therefore, when a current texture block in a dependent view is coded according to VSP by backward warping the current texture block to the reference picture using an associated depth block and the motion parameter inheritance (MPI) mode is selected for the corresponding depth block in the dependent view, the corresponding depth block in the dependent view is encoded or decoded using non-VSP inter-view prediction based on motion information inherited from the current texture block.

1. A method for three-dimensional or multi-view video encoding or decoding, the method comprising:
receiving a reference picture in a reference view; receiving input data associated with a current texture block in a dependent view; generating view synthesis prediction (VSP) data for the current texture block by backward warping the current texture block to the reference picture using an associated depth block; encoding or decoding the current texture block using the VSP data; and encoding or decoding a corresponding depth block in the dependent view using non-VSP inter-view prediction based on motion information inherited from the current texture block, wherein the corresponding depth block is collocated with the current texture block.
