DEPTH MODELING MODE CODING AND DECODING METHOD AND VIDEO CODEC

摘要

The invention discloses a depth modeling mode coding and decoding method as well as a video codec, for the case where the CTLB is inter mode coding or when the CTLB is intra mode coding but an intra mode coding mode is 0 or 1. The coding method comprises: constructing a coarse set of Wedgelet patterns from prediction modes of a depth prediction unit; selecting an optimal Wedgelet pattern from the coarse set of Wedgelet patterns; coding index information of the optimal Wedgelet pattern, and performing depth modeling mode coding according to the optimal Wedgelet pattern. The embodiments of the invention greatly decrease decoding complexity, shortens decoding time by 2% and has little influence on compression efficiency.
