METHOD AND APPARATUS of INTER-VIEW SUB-PARTITION PREDICTION in 3D VIDEO CODING

摘要

A method and apparatus for three-dimensional video encoding or decoding using sub-block based inter-view prediction are disclosed. The method partitions a texture block into texture sub-blocks and determines disparity vectors of the texture sub-blocks. The inter-view reference data is derived based on the disparity vectors of the texture sub-blocks and a reference texture frame in a different view. The inter-view reference data is then used as prediction of the current block for encoding or decoding. One aspect of the present invention addresses partitioning the current texture block. Another aspect of the present invention addresses derivation of disparity vectors for the current texture sub-blocks.

1. A method for three-dimensional video encoding or decoding, the method comprising:
receiving first data associated with a current block of a current frame corresponding to a current view; partitioning the current block into current sub-blocks; determining disparity vectors of the current sub-blocks; deriving inter-view reference data from a reference frame based on the disparity vectors of the current sub-blocks, wherein the reference frame and the current frame correspond to different views, and the reference frame and the current frame have a same picture timestamp; and applying inter-view predictive encoding or decoding to the first data based on the inter-view reference data.
