Binocular vision: The neural integration of depth and motion
Recent experiments have provided new clues as to how, in visual perception, three-dimensional depth is signaled and integrated with image motion.
متن کاملNeural 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...
متن کاملComparing depth from motion with depth from binocular disparity.
The accuracy of depth judgments that are based on binocular disparity or structure from motion (motion parallax and object rotation) was studied in 3 experiments. In Experiment 1, depth judgments were recorded for computer simulations of cones specified by binocular disparity, motion parallax, or stereokinesis. In Experiment 2, judgments were recorded for real cones in a structured environment,...
متن کاملIntegration of motion information during binocular rivalry
When two moving gratings are superimposed in normal viewing they often combine to form a pattern that moves with a single direction of motion. Here, we investigated whether the same mechanism underlies pattern motion when drifting gratings are presented independently to the two eyes. We report that, with relatively large circular grating patches (4 deg), there are periods of monocular dominance...
متن کاملEarly computational processing in binocular vision and depth perception.
Stereoscopic depth perception is a fascinating ability in its own right and also a useful model of perception. In recent years, considerable progress has been made in understanding the early cortical circuitry underlying this ability. Inputs from left and right eyes are first combined in primary visual cortex (V1), where many cells are tuned for binocular disparity. Although the observation of ...
