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

Depth-Image-Based-Rendering (DIBR) is fundamental to 3D-TV applications because the generation of new viewpoints is recurrent. Like 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 3D-TV applications: either in a 2D context (Free Viewpoint Television, FTV), or in a 3D context (3D displays reproducing stereos-copic vision). Depending on the context, the factors affecting the visual expe-rience may differ. This chapter concerns the case of the use of DIBR in the 2D context. It addresses two particular cases of use: visualization of still images and visualization of video sequences, in FTV in the 2D context. Through these two cases, the main issues of DIBR are presented in terms of visual quality assess-ment. 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 sequence assessment. The two experiments question the reliability of subjective and objective usual tools when assessing the visual quality of synthesized views in a 2D context
