Method and Apparatus of Candidate Generation for Single Sample Mode in Video Coding

摘要

A method and apparatus of video coding for a block of depth data or texture data coded in SSM (Single Sample Mode) are disclosed. Embodiments according to the present invention construct a sample candidate list comprising one or more single color candidates corresponding to one or more representative samples of one or more previous SSM-coded blocks, or one or more palette color candidates corresponding to one or more previously used colors in one or more previous palettes associated with one or more palette-coded blocks, or both. A selected sample candidate is then determined from the sample candidate list and the selected sample candidate is used to encode or decode the current block by representing the whole current block by this selected sample candidate. Spatial and/or temporal candidates from previously SSM-coded blocks can also be included in the sample candidate list.

1. A method of video coding for a block of depth data or texture data coded in SSM (Single Sample Mode), the method comprising:
receiving input data associated with a current block, wherein the current block corresponds to a depth block or a texture block; constructing a sample candidate list comprising one or more single color candidates corresponding to one or more representative samples of one or more previous SSM-coded blocks, or one or more palette color candidates corresponding to one or more previously used colors in one or more previous palettes associated with one or more palette-coded blocks, or both of said one or more single color candidates and said one or more palette color candidates; determining a selected sample candidate from the sample candidate list; and encoding the current block by representing all samples in the current block by said selected sample candidate at an encoder side, or decoding the current block by using said selected sample candidate as a reconstructed value for all samples in the current block at a decoder side.
