Abstract

3D Video system based on Depth-Image-Based Rendering relies on high quality depth data. Errors distributed randomly in depth map sequences induce annoying temporal noise, such as flickering and object shifting. Prior studies on video quality assessment focused mainly on spatial quality of the tested sequence and often ignored its temporal performance. In synthesized sequences, a large number of tiny geometric distortions and illumination differences are temporally constant and perceptually invisible. The dynamic noise impairs subjective quality of the sequences more greatly than the static spatial noise. Temporal quality plays a dominant role in overall quality assessment on the synthesized sequences with temporal instability problem. We propose a simple full-reference metric, Peak Signal to Perceptible Temporal Noise Ratio, to evaluate quality of synthesized sequences by measuring the perceptible temporal noise in them.
