Abstract:
This disclosure describes techniques for 3D video coding. In particular, this disclosure is related to techniques for advanced residual prediction (ARP) in 3D-HEVC. According to one techniques of this disclosure, when performing inter-view ARP for a bi-directionally predicted block, the video coder may determine a motion vector for a first corresponding block as part of performing ARP for a first prediction direction and reuse that determined motion vector when performing ARP for a second prediction direction. According to another technique, for a bi-directionally predicted block, a video coder may apply ARP in only one direction for a chroma component of a block but apply ARP in two directions for a luma component of the block. According to another technique, a video coder may selectively apply ARP to chroma components based on block size. These simplifications, as well as other techniques included in this disclosure, may reduce overall coding complexity.
