Method of Sub-Prediction Unit Inter-View Motion Prediction in 3D Video Coding

摘要

A method for a three-dimensional encoding or decoding system incorporating sub-block based inter-view motion prediction is disclosed. The system utilizes motion or disparity parameters associated with reference sub-blocks in a reference picture of a reference view corresponding to the texture sub-PUs split from a current texture PU (prediction unit) to predict the motion or disparity parameters of the current texture PU. Candidate motion or disparity parameters for the current texture PU may comprise candidate motion or disparity parameters derived for all texture sub-PUs from splitting the current texture PU. The candidate motion or disparity parameters for the current texture PU can be used as a sub-block-based inter-view Merge candidate for the current texture PU in Merge mode. The sub-block-based inter-view Merge candidate can be inserted into a first position of a candidate list.

1. A method for three-dimensional or multi-view video encoding or decoding, the method comprising:
receiving input data associated with one or more motion or disparity parameters of a current texture PU (prediction unit) in a dependent view; splitting the current texture PU into texture sub-PUs; locating reference sub-blocks in a reference picture of a reference view corresponding to the texture sub-Pus; identifying said one or more motion or disparity parameters of the reference sub-blocks; and encoding or decoding said one or more motion or disparity parameters of the current texture PU based on said one or more motion or disparity parameters of the reference sub-blocks.
