Measuring the perceived visual realism of images
Pablo Mauricio Rademacher, Gary J. Bishop · 2003
One of the main goals of computer graphics research is to develop techniques for creating images that look real -- i.e., indistinguishable from photographs. Most existing work on this problem has focused on image synthesis methods, such as the simulation of the physics of light transport and the reprojection of photographic samples. However, the existing research has been conducted without a clear understanding of how it is that people determine whether an image looks real or not real. There has never been an objectively tested, operational definition of realism for images, in terms of the visual factors that comprise them. If the perceptual cues behind the assessment of realism were understood, then rendering algorithms could be developed to directly target these cues. This work
