Abstract :
In this paper a study on the perceived quality that results of chromatic variations in 3D video is reported. The testing videos were represented in the CIE 1976 (L*a*b*) color space, and their colors were initially subdivided into clusters based on their similarity. Predefined chromatic errors were applied to these color clusters. These videos were shown to subjects that were asked to rank their quality based on the colors naturalness. The Mean Opinion Scores were computed and the sensibility to chromatic changes on 3D video was quantified. Moreover, attention maps were obtained and a short study on the changes of the visual saliency in the presence of these chromatic variations is also reported.
