METHOD OF SIGNALING FOR DEPTH-BASED BLOCK PARTITIONING

摘要

A method of signaling depth-based block partitioning (DBBP) for multi-view or three-dimensional (3D) video coding is disclosed. In one embodiment, the DBBP flag is signaled for all candidate prediction modes of the current texture coding unit including a non-2N×N partition mode. The group of candidate prediction modes may consist of 2N×N partition mode and N×2N partition mode. If the DBBP flag indicates the DBBP being used for the current texture coding unit, DBBP encoding is applied to the current texture coding unit or DBBP decoding is applied to one or more PUs associated with the current texture coding unit to recover the current texture coding unit. If the DBBP flag indicates the DBBP being not used for the current texture coding unit, a prediction partition mode is signaled at an encoder side or parsed at a decoder side from a CU (coding unit) level of the bitstream.

1. A method of signaling depth-based block partitioning (DBBP) for multi-view or three-dimensional (3D) video decoding, the method comprising:
receiving a bitstream including coded data of a current texture coding unit in a texture picture; determining a prediction partition mode from a group of candidate prediction modes including a non-2N×N partition mode for the current texture coding unit to partition the current texture coding unit into one or more prediction units according to the prediction partition mode; parsing a DBBP flag from the bitstream for all candidate prediction modes of the current texture coding unit including the non-2N×N partition mode; and if the DBBP flag indicates the DBBP being used for the current texture coding unit, deriving one or more prediction units associated with the current texture coding unit from the bitstream and applying DBBP decoding to the coded current texture coding unit to recover the current texture coding unit.
