Abstract
This paper proposes a new temporal consistency measure for quality assessment of synthesized video. Disocclusion regions appear hole regions of the synthesized video at virtual viewpoints. Filling hole regions could be problematic when the synthesized video is perceived through multi-view displays. In particular, the temporal inconsistency caused by hole filling process in view synthesis could affect the perceptual quality of the synthesized video. In the proposed method, we extract excessive flicker regions between consecutive frames and quantify the perceptual effects of the temporal inconsistency on them by measuring the structural similarity. We have demonstrated the validity of the proposed quality measure by comparisons of subjective ratings and existing objective metrics. Experimental results have shown that the proposed temporal inconsistency measure is highly correlated with the overall quality of the synthesized video.
