Method and apparatus of depth prediction mode selection

摘要

There is disclosed a method, apparatus and computer program product for prediction mode selection for coding a block of a depth map. An ordered list of coding modes is obtained, wherein the ordered list of coding modes comprises a plurality of coding modes each of which is capable of being used for coding of the block. A plurality of depth modeling modes (DMMs) each of which is capable of being used for coding of the block are obtained. And whether a DMM of the plurality of DMMs is to be added into the ordered list of coding modes in accordance with a decision condition is determined.

1. A method for a pre-selection process in encoding a block of depth data for a video frame, comprising:
obtaining a list including one or more depth data coding modes; updating the list with at least one or more Depth Modeling Modes (DMMs); selecting one or more depth data coding modes from the list to encode the block of depth data for the video frame; and encoding at least one block of depth data for a video frame according to the selection of the one or more depth data coding modes; when a first mode in the list of the one or more depth data coding modes is not a planar coding mode, and a second mode in the list of the one or more depth data coding modes is a DC mode, adding the one or more DMMs into the list; when a first mode in the list of the one or more depth data coding modes is a planar coding mode, and a size of a Coding Unit (CU) is larger than 4×4, adding the one or more DMMs into the list, wherein the block of the depth data comprises one or more CUs; when a first mode in the list of the one or more depth data coding modes is a planar coding mode, adding the one or more DMMs into the list when a second mode in the list of the one or more depth data coding modes is a DC mode; and adding a different one or more DMMs into the list when the second mode in the list of the one or more depth data coding modes is not a DC mode.
