Wedgelet pattern extension for depth intra coding

摘要

Techniques are described determining a partition pattern for intra-prediction encoding or decoding a depth block from a partition pattern of one or more partition patterns associated with smaller sized blocks. A video encoder may intra-prediction encode the depth block based on the determined partition pattern, and a video decoder may intra-prediction decode the depth block based on the determine partition pattern.

1. A method of decoding video data, the method comprising:
constructing a partition pattern list that includes one or more partition patterns associated with a block of a first size; receiving an index into the partition pattern list; determining a partition pattern associated with the block of the first size based on the received index into the partition pattern list; determining a partition pattern for a depth block of a second size based on the determined partition pattern associated with the block of the first size, wherein the second size is larger than the first size, and wherein the depth block is a block of a depth map in a framework of three-dimensional (3D) video coding; and intra-prediction decoding the depth block based on the determined partition pattern for the depth block without intra-prediction decoding the block of the first size using the determined partition pattern associated with the block of the first size.
