“…Thus, it is essential to compress these stereo data efficiently. Many researchers dedicate to employ both temporal and inter-view predictions to improve the coding efficiency of stereo video [4][5][6][7]. A pixel-based joint estimation utilizing the motion-disparity constraint is proposed to enhance the coding efficiency [8].…”

In order to exploit the intra-view and inter-view dependencies in stereo video coding, a fast joint motion and disparity estimation algorithm is proposed in this paper. An efficient search strategy based on the motion-disparity constraint is developed, in which both the motion and disparity vectors can be obtained simultaneously with low complexity. Moreover, a credible initial predictive vector set is designed with the aid of the temporal and spatial neighboring blocks so that the coding efficiency can be further enhanced. The experimental results demonstrate that the proposed algorithm can reduce more than 96% coding time compared with the JMVM full search with a negligible quality drop.
