binocular disparity

n
(Physiology) physiol the small differences in the positions of the parts of the images falling on each eye that results when each eye views the scene from a slightly different position; these differences make stereoscopic vision possible

These differences in the images are called "binocular disparity" and the entire process is called "binocular vision".
To exclude the inferences of each pathological factor on the individuals, binocular disparity was applied to the analysis of results.
We have been researching the cues to accommodation and convergence for many years, using a method by which we can tease out the relative contributions of blur, binocular disparity and proximal /looming cues as children grow.
Although human perceptual responses to binocular disparity have been studied extensively [14], there have been relatively few studies of how human cortical activity is related to stereo depth perception.
In practice, binocular disparity is attributed to the primary visual cortical areas, and it is one of the most important stereo cues.
Maddox's second component was reflex convergence which responds automatically to binocular disparity to correct any error between the to be fixated object and the intersection of the visual axes.
The horizontal progressive mirror, Lee said, does have some problems with binocular disparity (the slight difference between the viewpoints of a person's two eyes) and astigmatism (blurring of a viewed image due to the difference between the focusing power in the horizontal and vertical directions).
These units correspond to the virtual space constructed by observers' visual system from binocular disparity information.
There is strong evidence (Cumming and Parker, 1994) that stereo-motion is mainly .detected by means of temporal changes in binocular disparity instead of inter-ocular velocity differences.
Stereoscopic displays, such as helmet-mounted displays and shutter glasses (e.g., CrystalEyes, StereoGraphics, Inc.) can add binocular disparity and convergence depth cues to reinforce the perception of depth.
The abilities of new display technologies regarding reproduction of important visual cues, such as binocular disparity, accommodation, or motion parallax, outperform the capabilities of methods for optimizing graphics content to match the requirements of particular hardware designs.
showed that high-fatigue caused by excessive binocular disparity intensified the IPS regions than the low-fatigue group did [11].
