12 February 2007 Perceptual quality evaluation of geometric distortions in images
Author Affiliations +
Human perception of image distortions has been widely explored in recent years, however, research has not dealt with distortions due to geometric operations. In this paper, we present the results we obtained by means of psychovisual experiments aimed at evaluating the way the human visual system perceives geometric distortions in images. A mathematical model of the geometric distortions is first introduced, then the impact of the model parameters on the visibility of the distortion is measured by means of both objective metrics and subjective tests.
