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 quali... 相似文献

The quality of virtual view based on multi-view video (MVD) plus depth format is often evaluated by PSNR or subjectively judged.
However, due to synthesizing arbitrary view images, the virtual view images mostly have no reference images and are only assessed
using non-reference. Virtual view images synthesized by depth estimation reference software (DERS) and view synthesis reference
software (VSRS) often accompanied with blockiness and other distortions on the edge. In addition, matching level for the depth
map and the corresponding texture maps of left and right views also affects the quality of the virtual view. This paper compares
the edge similarity of the depth and the corresponding texture maps which generate the intermediate virtual view and combined
with the virtual view’s blockiness which causing blur to evaluate the quality of the virtual view. Experiment results show
that the proposed method can reflect the quality of the virtual view better. 相似文献
