In a multiview video plus depth (MVD) based three-dimensional (3D) video system, the generation of the contents with simultaneous resolution and depth adjustments is very challenging. In this paper, we have presented a Multiview Video plus Depth ReTargeting (MVDRT) technique for stereoscopic 3D (S3D) displays. The main motivation of this work is to optimize the resolution and depth of original MVD data so that it is suitable for view synthesis. Our method takes shape preservation, line bending and visual comfort constraints into account, and simultaneously optimizes the horizontal, vertical and depth coordinates in display space. The retargeted MVD data is used to generate the contents for S3D displays. Experimental results demonstrate our method can achieve a better view synthesis performance than other approaches that still preserve the original depth information after retargeting, leading to promising S3D experience.
