3DTV has been widely studied these last years from a technical point of view but the related quality evaluations does not follow this enthusiasm. This article reviews the quality assessment for 3DTV. Compared to 2D quality measure, the third dimension adds several new problems and quality assessment becomes a complex issue. Nevertheless, efforts made for 2D content quality estimation can be used for an extension to 3D. In this paper we propose a first attempt to adapt such 2D metrics to 3D content and add the contribution of a measure of the distortion on the disparity map for stereoscopic image pairs. This 3D metric performances has been evaluated with subjective tests.
