US 2015/0030073 A1 · SUB-PU MOTION PREDICTION FOR TEXTURE AND DEPTH CODING

Abstract

In accordance with one or more techniques of this disclosure, a video coder may divide a current prediction unit (PU) into a plurality of sub-PUs. Each of the sub-PUs may have a size smaller than a size of the PU. Furthermore, the current PU may be in a depth view of the multi-view video data. For each respective sub-PU from the plurality of sub-PUs, the video coder may identify a reference block for the respective sub-PU. The reference block may be co-located with the respective sub-PU in a texture view corresponding to the depth view. The video coder may use motion parameters of the identified reference block for the respective sub-PU to determine motion parameters for the respective sub-PU.
