Threshold and Suprathreshold Lateral Spatial Interactions in Brightness, Contrast and Stereoscopic Depth Perception.
Abstract
We measured the effects of stereoscopic and pictorial depth separation on a variety of phenomena involving lateral interactions in the luminance and contrast domains (e.g., grating induction, perceptual transparency, simulataneous brightness contrast and contrast-contrast). In addition, the early visual mechanisms underlying the formation of illusory contours were assessed by measuring the effects of illusory contours on the visibility of spatiotemporally limited targets (i.e., Gabor patches); and by measuring the effects of filtered noise textures on the strength of illusory contours. Finally, the temporal characteristics of the mechanisms underlying grating induction and simultaneous brightness contrast were measured.
