Binocular detection of disparate light flashes

Vision Research, 1977
Abstract In a series of experiments forced-choice detection of small parafoveally viewed light flashes was examined under various conditions of binocular stimulation. When both eyes were stimulated either on corresponding retinal points or on slightly disparate points (6′) detection performance was greater than expected on the basis of probability ...

Movement Aftereffects Contingent on Binocular Disparity

Perception, 1974
Five subjects adapted for 30 min to a textured disc lying in front of the fixation point with 0·1 deg(1) crossed disparity, which rotated clockwise at 4 rev/min, alternating with a disc behind the fixation point, with 0·1 deg of arc uncrossed disparity, which rotated anticlockwise.

Binocular Receptive Field Models, Disparity Tuning, and Characteristic Disparity

Neural Computation, 1996
Disparity tuning of visual cells in the brain depends on the structure of their binocular receptive fields (RFs). Freeman and coworkers have found that binocular RFs of a typical simple cell can be quantitatively described by two Gabor functions with the same gaussian envelope but different phase parameters in the sinusoidal modulations (Freeman and ...

Binocular unmasking with vertical disparity.

Canadian Journal of Psychology / Revue canadienne de psychologie, 1991
We recently found (Schneider, Moraglia, & Jepson, 1989) that the contrast threshold for the detection of a visual signal in a noisy background can be considerably lower when binocular cues are available then when monocular cues only are present. Here, we investigated the occurrence of binocular unmasking with vertical interocular disparities.

Active detection of binocular disparities

Proceedings IROS '91:IEEE/RSJ International Workshop on Intelligent Robots and Systems '91, 2002
The authors propose an active algorithm to detect binocular disparities without using additional constraints. It is based on the motion parallax obtained by the moving monocular camera. The search range of binocular disparity is restricted based on the monocular motion parallax.

Binocular Disparity and Head-Up Displays

Human Factors: The Journal of the Human Factors and Ergonomics Society, 1980
Collimation errors present in displays such as the head-up display (HUD) will produce retinal disparity on the retinae of the observer and will have the effect of altering the spatial location of the display. It is apparent that this can, in some instances, give rise to visual discomfort. Psychophysical methods were used to examine the sensitivity and

Spatial organization of binocular disparity sensitivity

Vision Research, 1975
Abstract The range of sensitivity to spatial modulation of disparity in a vertical line was investigated. The function obtained was not greatly altered by conditions of fixed aperture, constant number of cycles, high resolution, foveal or eccentric presentation.

A Disparity Gradient Limit for Binocular Fusion

Science, 1980
Ever since Panum, it has been commonly assumed that there is an absolute disparity limit for binocular fusion. It is now found that nearby objects modify this disparity limit. This result sheds new light on several enigmatic phenomena in stereopsis.

Fixation Disparity vs. Binocular Fixation Misalignment

Optometry and Vision Science, 1985
Conventional fixation disparity was compared with the corresponding foveal fixation misalignment measured by a recently developed method based on the effect of retinal eccentricity on the width of the border enhancement band. Unlike procedures using binocular nonius alignment, the method is not subject to adaptive changes in perceived direction. Forced
