Model of perceptual image fidelity

Research output: Chapter in Book/Report/Conference proceedingConference contribution


An extension of the authors' work on perceptual image distortion is presented. The extended model accounts for (1) contrast sensitivity as a function of spatial frequency, mean luminance and spatial extent, (2) luminance masking, and (3) contrast masking. In a typical spatial pattern detection experiment, the contrast of a visual stimulus called the target is adjusted until it is just barely detectable. Threshold contrasts of the target are measured over a range of spatial frequencies, mean luminances, and spatial extents. The model consists of three main parts: a retinal component for contrast sensitivity, a cortical component for contrast masking, and a detection mechanism.
