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 ...

Stereo Day-for-Night: Retargeting Disparity for Scotopic Vision [PDF]
ACM Transactions on Applied Perception, 2014 Several approaches attempt to reproduce the appearance of a scotopic low-light night scene on a photopic display (“day-for-night”) by introducing color desaturation, loss of acuity, and the Purkinje shift toward blue colors. We argue that faithful stereo reproduction of night scenes on photopic stereo displays requires manipulation of not only color ...

A vision fronted with a new disparity model [PDF]
, 2004 We are developing a frontend that is based on the image representation in the visual cortex and plausible processing schemes. This frontend consists of multiscale line/edge and keypoint (vertex) detection, using models of simple, complex and end ...

Disparities in Vision Health and Eye Care
Ophthalmology, 2022 Significant disparities in vision health and eye care exist. To achieve health equity, we must understand the root causes and drivers of health disparities and inequities, including social determinants of health and systemic racism.

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.

Stereo vision requires an explicit encoding of vertical disparity [PDF]
Journal of Vision, 2009 Vertical disparities influence the perception of 3D depth, but little is known about the neuronal mechanisms underlying this. One possibility is that these perceptual effects are mediated by an explicit encoding of two-dimensional disparity. Recently, J. C. A. Read and B. G.

The use of cues to convergence and accommodation in naive, uninstructed participants [PDF]
, 2008 A remote haploscopic video refractor was used to assess vergence and accommodation responses in a group of 32 emmetropic, orthophoric, symptom free, young adults naïve to vision experiments in a minimally instructed setting.
