Analysis of Motion Vector Predictor in Multiview Video Coding System

In this paper, various motion vector predictors are analyzed and their selection method is proposed for 3D video coding. In a ubiquitous multimedia system, video compression has been expected to be an important element since an available bandwidth is very limited. In the proposed method, several motion vector predictors are competed each other with the slightly modified rate-distortion criterion. Spatial, temporal, and inter-view predictors are considered as motion vector predictors to reduce spatial, temporal, and interview redundancies, respectively. The proposed method increases the motion vector coding efficiency by selecting the best motion vector predictor among them. Accordingly, overall bit rates are reduced by 5.2 % in average, up to 6.1 %compared to reference software JMVC 6.0 in terms of the Bjontegaard Metric.
