中文摘要：

深度地图被用于合成在免费观点的电视(FTV ) 的虚拟看法系统。当深度地图用存在深度评价方法被导出时，深度失真将在综合看法引起不受欢迎的人工制品。解决这个问题，为虚拟看法合成和深度的地图(D-3DV ) 印射在 FTV 应用程序编码的 3D 录像质量模型库深度被建议。首先，在在编码深度地图和显示的看法的失真之间的关系被导出。然后，一精确， 3DV 质量模型基于深度特征为综合虚拟看法发展。基于 D-3DV 模型，最后，多边的过滤作为一个预先处理的过滤器被使用减少显示人工制品。客观、主观的方法评估的试验性的结果显示建议 D-3DV 模型能减少编码的深度的小点率并且更好完成显示质量。

英文摘要：

Depth maps are used for synthesis virtual view in free-viewpoint television （FTV） systems. When depth maps are derived using existing depth estimation methods, the depth distortions will cause undesirable artifacts in the synthesized views. To solve this problem, a 3D video quality model base depth maps （D-3DV） for virtual view synthesis and depth map coding in the FTV applications is proposed. First, the relationships between distortions in coded depth map and rendered view are derived. Then, a precisely 3DV quality model based depth characteristics is develop for the synthesized virtual views. Finally, based on D-3DV model, a multilateral filtering is applied as a pre-processed filter to reduce rendering artifacts. The experimental results evaluated by objective and subjective methods indicate that the proposed D-3DV model can reduce bit-rate of depth coding and achieve better rendering quality.
