Visual quality assessment of synthesized views in the context of 3D-TV

DIBR is fundamental to 3DTV applications because the generation of new viewpoints is recurrent. As any tool, DIBR methods are subject to evaluations thanks to the assessment of the visual quality of the resulting generated views. This assessment task is peculiar because DIBR can be used for different 3DTV applications: either in a 2D context (free viewpoint video), or in a 3D context (3D displays reproducing stereoscopic vision). Depending on the context, the factors affecting the visual experience may differ. This chapter concerns the case of use of DIBR in the 2D context. It addresses two particular cases of use, in FTV: visualization of still images and visualization of video sequences, in the 2D context. Through these two cases, the main issues of DIBR are presented, in terms of visual quality assessment. Two experiments are proposed as case studies addressing the problematic of this chapter: the first one concerns the assessment of still images and the second one concerns the video sequences assessment. The two experiments question the reliability of subjective and objective usual tools when assessing the visual quality of synthesized view in a 2D context.
