Abstract:

Binocular disparity is a precise depth cue yet in view of its derivation from binocular geometry. it is generally considered to be independent of luminance contrast. Our study, however, demonstrates a profound effect of luminance contrast on perceived depth from disparity. Such results cannot be explained by the existing disparity energy models because it would predict no effect of luminance contrast on depth perception. Instead, we conducted a multi-stage model that involves a contrast gain control mechanism followed by the disparity averaging to account for the luminance contrast effect on perceived depth from disparity.
