Using disparity for quality assessment of stereoscopic images
Alexandre Benoît, Patrick Le Callet, Patrizio Campisi, Romain Cousseau · 2008
3DTV has been widely studied these last years from a technical point of view but the related perceived quality evaluations do not follow this hype. This paper firstly reviews quality assessment issues for 3DTV. Compared to 2D quality measure, depth information adds several new problems considering quality assessment. Nevertheless, efforts made for 2D content quality estimation can be used for an extension to 3D. In a second part, this paper proposes an adaptation of 2D metrics to 3D in the context of coding artifacts and stereoscopic images. Distortion on disparity is introduced to improve conventional 2D metrics. Performances have been evaluated using subjective tests.
