Effect of Global and Local Brightness on Quality of 3D and 2D Visual Perception
There are several different factors that affect the perceived quality of 3D content. The authors' objective in this paper is to investigate how the global and local change of brightness in a scene will affect the overall 3D visual perception. Their work contains two studies: global change of brightness, which is achieved by setting different exposure times on the camera, and local change of brightness, where the brightness of the background is consistent and the object's brightness is changed using an external light source and/or a reflector disk. Subjective evaluations were performed, with the subjects being asked to rate the 3D perceptual quality of each sequence.
