Quality assessment and perception in computer graphics

The computer graphics community has successfully exploited our knowledge about the human visual system and its limitations for years. The perceptual computer graphics domain is a rich research area, and the understanding of human vision mechanisms and their integration in the computer graphics processes are becoming increasingly crucial in most applications. This special issue represents a good sample of the huge diversity of challenges in the perceptual computer graphics area: aesthetics evaluation, user gaze analysis, shape perception, and the wide scope of targeted applications
