Quality Assessment of a Stereo Pair Formed From Decoded and Synthesized Views Using Objective Metrics

Touradj Ebrahimi, Philippe Hanhart

When a stereo pair is formed from a decoded view and a synthesized view, it is unclear how the overall quality of the stereo pair should be assessed through objective quality metrics. In this paper, this problem is addressed considering a 3D video represen ...
