Binocular Depth Perception without Familiarity Cues.

The reported phenomena were obtained through the use of special techniques. (i) All monocular depth and familiarity cues were removed from the stimuli (through the use of randomdot stereo patterns). (ii) The statistical and topological properties of the stimuli were precisely known (since they were generated according to a specific computer program). (iii) Convergence motions of the eye and pro...

Neural models of binocular depth perception.

We have known since Wheatstone (1838) that disparities between images presented to the two eyes induce a strong sensation of depth. More recent experiments with random-dot stereograms have shown that disparity is a sufficient cue for stereopsis (Julesz 1960, 1971). Disparity-tuned neurons in visual cortex were first demonstrated in the cat (Barlow et al. 1967; Nikara et al. 1968; Pettigrew et a...

Physiologically based models of binocular depth perception

Stereoscopic Depth Perception during Binocular Rivalry

When we view nearby objects, we generate appreciably different retinal images in each eye. Despite this, the visual system can combine these different images to generate a unified view that is distinct from the perception generated from either eye alone (stereopsis). However, there are occasions when the images in the two eyes are too disparate to fuse. Instead, they alternate in perceptual dom...
