Stereopsis and binocular rivalry.
Stereopsis and binocular rivalry appear to be incompatible. Rivalry involves suppression of input from one eye at each location in space and time, whereas Stereopsis requires the combination of information from both eyes to yield a sensation of depth. This article presents a theory of the relationship of these phenomena. Evidence from previous work and from experiments reported here shows that ...
متن کاملHysteresis effects in stereopsis and binocular rivalry
Neural hysteresis plays a fundamental role in stereopsis and reveals the existence of positive feedback at the cortical level [Wilson, H. R., & Cowan, J. D. (1973). A mathematical theory of the functional dynamics of cortical and thalamic nervous tissue. Kybernetik 13(2), 55-80]. We measured hysteresis as a function of orientation disparity in tilted gratings in which a transition is perceived ...
متن کاملBinocular Rivalry
When two different images are shown, one to each eye, we don't always see a mix of the two. In cases when the images differ in atleast one attribute we may see only one image at a time and this alternates between the two images. (eg: Horizontal and vertical gratings differ in the direction of grating. When horizontal grating is shown to say right eye and vertical grating to left eye we see only...
متن کاملBinocular rivalry
What is binocular rivalry? In humans and animals with forward facing eyes, the two eyes provide views of the world that are only subtly different from one another. In each eye, the lens focuses light into a two-dimensional image on the retina. In normal vision, the disparity between the retinal images provides a stereoscopic cue to the third spatial dimension, depth. But when the eyes are prese...
متن کاملBinocular Helmholtz Stereopsis
Helmholtz stereopsis has been introduced recently as a surface reconstruction technique that does not assume a model of surface reflectance. In the reported formulation, correspondence was established using a rank constraint, necessitating at least three viewpoints and three pairs of images. Here, it is revealed that the fundamental Helmholtz stereopsis constraint defines a nonlinear partial di...
