Quality Improved Neighbor Block Disparity Vector Derivation in 3D-HEVC

ZHOU Zuo-cheng;JIA Ke-bin;Beijing Laboratory of Next Generation Information Network,College of Electronic Information and Control Engineering,Beijing University of Technology;  
Neighboring block disparity vector derivation in 3D High Efficiency Video Coding( 3D-HEVC) is a key technology to get the disparity vector. To improve the quality of the disparity vector derived from the fast algorithm,we propose a proportion combination and group searching method to get the NBDV. We first changed the rule that takes the first search DV as final NBDV,and then divide the searching candidates into several groups for the proportion combination,after that design a strategy to search the candidates in several groups. The simulation results showthat the proposed algorithm has improved the coding quality with negligible coding time loss.
