Analysis of maximum tolerant depth distortion in view synthesis

In view synthesis, pixels in an original view are warped into a virtual view with depth-image-based rendering (DIBR). During the procedure of DIBR, distortions in depth map may lead to geometric errors in the synthesized view which will induce quality degradation of synthesized view. Therefore, how to efficiently preserve the fidelity of depth information is extremely important. In this paper, we explore and develop a maximum tolerable depth distortion (MTDD) model to examine the allowable depth distortion which will not introduce any texture distortion for a rendered virtual view and accordingly develop. Experimental results show that a virtual view can be synthesized without introducing any geometric changes if depth distortions follow the MTDD specified thresholds.
