  The emergence of multiview displays has made the need for synthesizing
virtual views more pronounced, since it is not practical to capture all of the
possible views when filming multiview content. View synthesis is performed
using the available views and depth maps. There is a correlation between the
quality of the synthesized views and the quality of depth maps. In this paper
we study the effect of depth map quality on perceptual quality of synthesized
view through subjective and objective analysis. Our evaluation results show
that: 1) 3D video quality depends highly on the depth map quality and 2) the
Visual Information Fidelity index computed between the reference and distorted
depth maps has Pearson correlation ratio of 0.75 and Spearman rank order
correlation coefficient of 0.67 with the subjective 3D video quality.
