Integration of Perspective and Disparity Cues in Surface
... It was proposed by Gibson (1950) that our visual system utilizes various kinds of depth cues to perceive the threedimensional (3D) shape of an object from two-dimensional (2D) retinal images. Visual depth is perceived not only with binocular cues of disparity, but also with monocular cues of linear ...
