US Patent 10009621 Advanced depth inter coding based on disparity of depth blocks

In one example, the disclosure is directed to techniques that include, for each prediction unit (PU) of a respective coding unit (CU) of a slice of a picture of the video data, determining at least one disparity value based at least in part on at least one depth value of at least one reconstructed depth sample of at least one neighboring sample. The techniques further include determining at least one disparity vector based at least in part on the at least one disparity value, wherein the at least one disparity vector is for the respective CU for each PU. The techniques further include reconstructing, based at least in part on the at least one disparity vector, a coding block for the respective CU for each PU.
