Low complexity Neighboring Block based Disparity Vector Derivation in 3D-HEVC

3D-HEVC incorporates advanced inter-view prediction techniques based on more accurately derived disparity vector to better exploit the correlation between objects in different views. The efficient disparity vector derivation method, namely, Neighboring Block based Disparity Vector Derivation (NBDV) provides disparity without accessing any depth information. The NBDV has been developed as a part of the 3D-HEVC in Joint Collaborative Team on 3D Video Coding (JCT-3V) for several meeting cycles, and adopted as a common coding tool used for all the inter-view prediction techniques for high efficient coding of texture views. This paper presents a low complexity NBDV, which is the state-of-the-art disparity vector derivation method in 3D-HEVC.
