Individual Objective and Subjective Fixation Disparity in Near Vision. [PDF]
PLoS ONE, 2017 Binocular vision refers to the integration of images in the two eyes for improved visual performance and depth perception. One aspect of binocular vision is the fixation disparity, which is a suboptimal condition in individuals with respect to binocular ...

Reliable Disparity Estimation Using Multiocular Vision with Adjustable Baseline
SensorsAccurate estimation of three-dimensional (3D) information from captured images is essential in numerous computer vision applications. Although binocular stereo vision has been extensively investigated for this task, its reliability is conditioned by the ...

Vector Disparity Sensor with Vergence Control for Active Vision Systems [PDF]
Sensors, 2012 This paper presents an architecture for computing vector disparity for active vision systems as used on robotics applications. The control of the vergence angle of a binocular system allows us to efficiently explore dynamic environments, but requires a ...

When is a disparity not a disparity? Toward an old theory of three-dimensional vision
i-Perception, 2023 The aims of this paper are twofold: first, to discuss and analyze the concept of binocular disparity and second, to contrast the traditional “air theory” of three-dimensional vision with the much older “ground theory,” first suggested by Ibn al-Haytham ...

Disparity Channels in Early Vision [PDF]
The Journal of Neuroscience, 2007 The past decade has seen a dramatic increase in our knowledge of the neural basis of stereopsis. New cortical areas have been found to represent binocular disparities, new representations of disparity information (e.g., relative disparity signals) have been uncovered, the first topographic maps of disparity have been measured, and the first causal ...

Binocular Vision: An Orientation to Disparity Coding [PDF]
Current Biology, 2002 A new study has shown that neurons in the visual cortex are specialized to encode the larger range of horizontal - relative to vertical - disparities that occurs in central vision. These results challenge the established 'energy' model of disparity processing.

Spatial properties of disparity pooling in human stereo vision
Vision Research, 1989 The spatial limits of disparity averaging were investigated using Julesz random dot stereograms with two different depth planes. Such stimuli could be perceived as two separate surfaces, one of which was seen through the transparent veil of the other, but under some conditions the depth of information provided by the two surfaces was pooled and the ...

Remote Sensing, 2019 Binocular disparity and motion parallax are the most important cues for depth estimation in human and computer vision. Here, we present an experimental study to evaluate the accuracy of these two cues in depth estimation to stationary objects in a static
