Method of Depth Coding Compatible with Arbitrary Bit-Depth

摘要

A method and apparatus for coding depth data using inter-view motion prediction (IVMP) in a three-dimensional or multi-dimensional video coding system are disclosed. In one embodiment, the bit depth of the depth data associated with the current depth map is determined first and a converted disparity vector is derived from a selected depth value depending on the bit depth. A corresponding depth block in an inter-view reference depth map in a reference view is located using the converted disparity vector. The current depth block is then encoded or decoded using the corresponding depth block as an inter-view predictor.

1. A method of coding depth data using inter-view motion prediction (IVMP) for a three-dimensional or multi-view video coding system, the method comprising:
receiving input data associated with a current depth block of depth data of a current depth map in a dependent view; determining a bit depth of the depth data associated with the current depth map; deriving a converted disparity vector from a selected depth value depending on the bit depth; locating a corresponding depth block in an inter-view reference depth map in a reference view using the converted disparity vector; and encoding or decoding the current depth block using the corresponding depth block as an inter-view predictor.
