... worth pointing out that dealing with stereo data introduces a new perspective; in fact instead of dealing with quality assessment we should refer to quality of experience. Indeed, since 3D involves new ... Therefore, in this paper, we take this fact into account and, starting from the metric designed in [15], we investigate the amount of information added, if any, into the quality asses...
