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.
在基于多视角视频加深度（MVD）的三维（3D）视频系统中，同时进行分辨率和深度调整来生成内容极具挑战性。在本文中，我们提出了一种用于立体3D（S3D）显示的多视角视频加深度重定目标（MVDRT）技术。这项工作的主要动机是优化原始MVD数据的分辨率和深度，使其适合视图合成。我们的方法考虑了形状保持、线条弯曲和视觉舒适度约束，并同时在显示空间中优化水平、垂直和深度坐标。重定目标后的MVD数据用于生成S3D显示的内容。实验结果表明，与其他在重定目标后仍保留原始深度信息的方法相比，我们的方法能够实现更好的视图合成性能，从而带来有前景的S3D体验。
