Efficient Disparity Computation without Maximum Disparity for Real-Time Stereo Vision

Procedings of the British Machine Vision Conference 2009, 2009
In order to improve the performance of correlation-based disparity computation of stereo vision algorithms, standard methods need to choose in advance the value of the maximum disparity (MD). This value corresponds to the maximum displacement of the projection of a physical point expected between the two images. It generally depends on the motion model,

Stochastic Approachres to Early Vision: Stereo Disparity

1990 Conference Record Twenty-Fourth Asilomar Conference on Signals, Systems and Computers, 1990., 2005
rl Ihe various task modules in early vision bear resemblances in processing visual cues. A successful model in one module can be adapted to other modules. In this paper, we investigate the applicability of stochastic models for computing disparity from a pair of images (stereo).

Binocular vision in infancy: Responsiveness to uncrossed horizontal disparity

Infant Behavior and Development, 2016
This research explored the onset of stereopsis, the ability to perceive depth from the different views provided by the two eyes. In a longitudinal study, infants were tested weekly from 6 to 20 weeks of age. The primary goal of the study was to establish the onset and the early development of sensitivity to uncrossed horizontal disparity.

Vertical disparity and binocular vision in the praying mantis

Visual Neuroscience, 1992
AbstractWe have investigated how the binocular control of prey capture in the praying mantis is affected by abnormally large vertical disparities, which were introduced by prisms placed in front of the eyes. The position of a target on the two retinae determines both the magnitude of head saccades made to fixate a target and its perceived distance ...

Mechanisms of stereoscopic vision: the disparity energy model

Current Opinion in Neurobiology, 1998
The past year has seen significant advances in our understanding of the role played by the primary visual cortex (V1) in stereoscopic vision. Recently, the mechanism by which complex cells in V1 respond to random-dot stereograms has been characterized; it appears that their response properties greatly reduce the complexity of one of the critical links ...

Disparities in Adult Vision Health in the United States

American Journal of Ophthalmology, 2012
To review the existing knowledge on vision health disparities in major adult vision health outcomes (age-related macular degeneration, diabetic retinopathy, glaucoma, cataract, refractive errors) and visual impairment and to identify knowledge gaps as related to the development of enhanced vision health surveillance in the United States.Literature ...

Dense disparity features for fast stereo vision

Proceedings of the 6th IEEE International Conference on Intelligent Data Acquisition and Advanced Computing Systems, 2011
A stereo vision algorithm suitable for fast dense stereo matching is proposed. This method extracts areas of uniform disparity or dense disparity features by testing candidate disparity estimates and classifying pixels according to a matching error. By commencing with a rigorous error threshold, pixels of reliable disparity values are identified.

Force and vision resolvability for assimilating disparate sensory feedback

IEEE Transactions on Robotics and Automation, 1996
Force and vision sensors provide complementary information, yet they are fundamentally different sensing modalities. This implies that traditional sensor integration techniques that require common data representations are not appropriate for combining the feedback from these two disparate sensor.
