Document Summary

9/5/13 8:02:00 am: depth perception- construct 3d mental representation of the visual world from 2d retinal input, depth perception - the use of the visual cues to estimate depth and distance, depth cues o binocular. Binocular disparity brain uses disparity between the two retinal images to compute distances of nearby objects. Convergence eye muscles turn eyes inward, brain knows how much the eyes are converging and uses this information to perceive distance o monocular. Distance cues that enable the perception of depth with one eye. Occlusion: near object occludes (blocks) an object that is farther away. Relative size: when we view 2 objects, we know to be the same size and one appears smaller than the other, we assume that the smallest is farther away. Familiar size: previous knowledge of object sizes aid in judging distance. Texture gradient: position relative to the horizon. Atmospheric perspective: the effect you get when far away objects take on the colors of atmospheric haze.
