Disparity tuning in mechanisms of human stereopsis.
The change in sensitivity across some stimulus dimension which follows adaptation to a particular stimulus can reveal a great deal about the tuning characteristics of underlying sensory/perceptual mechanisms. In this study, a psychophysical adaptation paradigm was employed to characterize the disparity tuning of perceptual mechanisms involved in stereopsis. The stimulus was a dynamic random-dot...
متن کاملStereopsis in the Presence of Binocular Disparity
Abstract The strongest evidence that pictorial cues contribute to stereopsis is the fact that the visual system appears to integrate both pictorial cues (such as perspective and shading) and optical cues (such as binocular disparity) into a single coherent percept. Indeed, when these sources of information are slightly in conflict the visual system appears to construct an entirely new object th...
متن کاملStereopsis, vertical disparity and relief transformations
The pattern of retinal binocular disparities acquired by a fixating visual system depends on both the depth structure of the scene and the viewing geometry. This paper treats the problem of interpreting the disparity pattern in terms of scene structure without relying on estimates of fixation position from eye movement control and proprioception mechanisms. We propose a sequential decomposition...
متن کاملStereopsis and Disparity Vergence in Monkeys with Subnormal Binocular Vision
The surgical treatment for strabismus in infants generally results in microtropia or subnormal binocular vision. Although the clinical characteristics of these conditions are well established, there are important questions about the mechanisms of binocular vision in these patients that can best be investigated in an appropriate animal model. In the present psychophysical investigations, spatial...
متن کاملBehavioral studies of local stereopsis and disparity vergence in monkeys
Investigations on macaque monkeys have provided much of our knowledge of the neural mechanisms of binocular vision, but there is little psychophysical data on the accuracy of vergence responses or the precision of stereoscopic depth perception in these primates. We have conducted comparative behavioral studies of binocular disparity processing in rhesus monkeys and humans via measurements of pr...
