abstract = {One of the main goals in realistic rendering is to generate images
that are indistinguishable from photographs -- but how do
observers decide whether an image is photographic or
computer-generated? If this perceptual process were understood,
then rendering algorithms could be developed to directly target
these cues. In this paper we introduce an experimental method for
measuring the perception of visual realism in images, and present
the results of a series of controlled human subject experiments.
These experiments cover the following visual factors: shadow
softness, surface smoothness, number of light sources, number of
objects, and variety of object shapes. This technique can be used
to either affirm or cast into doubt common assumptions about
realistic rendering. The experiments can be performed using either
photographs or computergenerated images. This work provides a
first step towards objectively understanding why some images are
perceived as photographs, while others as computer graphics.},
