Multiresolution fixation of a binocular vision system
Binocular camera fixation refers to the control of camera movements so that the optical axes of two cameras converge at a single point of interest in a three-dimensional scene. This thesis describes the theory and high-level algorithms for a procedure that can locate fixation points in an image …

The Effects of Binocular Vision Impairment on Adaptive Gait. The effects of binocular vision impairment due to monocular refractive blur on adaptive gait involving negotiation of a raised surface.
… was to extend knowledge regarding impairment of binocular vision and adaptive gait. Firstly using a 3D motion analysis system to measure how impairment of stereopsis affected adaptive gait during a negotiation of a step, secondly by determining which clinical stereotest was the most reliable for …

Investigating Gaze Orientation and Spatial Localization in Strabismus
Purpose: Disruption of binocular vision during the critical period of development results in strabismus in 3-5% of the population. The visual system adapts to this decorrelation with the help of suppressive mechanisms that influence eye choice behavior. The overall goal of this research was to …

Exploring neural responses in the human brain to real-world face size and distance
In natural binocular vision, three-dimensional (3D) geometry provides information about physical facial size and egocentric distance that can inform social behaviours. Yet most neuroimaging studies present two-dimensional stimuli at fixed distances and overlook 3D spatial cues. In this fMRI study, …

SP3X : a six-degree of freedom device for natural model creation
… physiologic capabilities in manual precision, binocular vision, and reach. The design also considers cost and manufacturability. This thesis presents prior and contributing research from industry, biology, and interfaces in academia. A study investigates the usability of the device and finds …

Interocular suppression and contrast gain control in human vision
… grating stimuli. Initial experiments focussed on binocular interactions within a single detecting mechanism, using contrast discrimination and contrast matching tasks. Consistent with previous findings, dichoptic presentation produced greater masking than monocular or binocular presentation. Four …

Requirement for AMPA receptor endocytosis and long-term depression in ocular dominance plasticity
… deprivation (MD). As in other mammals with binocular vision, MD in mice induces bidirectional plasticity: rapid weakening of responses evoked through the deprived eye is followed by delayed strengthening of open-eye responses. It has been proposed that these bidirectional changes occur …

CLINICAL USEFULNESS OF OCULAR TESTS FOR DIAGNOSING CONCUSSIONS
Dysfunctions of ocular motor and binocular vision are some of the most commonly observed problems in patients with severe traumatic brain injury. Secondarily, subjective complaints of compromised vision and ocular motor functions are also sometimes reported in mild traumatic brain injuries (mTBI). …

Adaptation to Interocular Differences in Blur
… so independently for the two eyes, and that the binocular adaptation of blur is determined largely by the sharper of the two eye's retinal images.

3D Object Detection from Images
Remarkable advancements in the field of Computer Vision, Artificial Intelligence and Machine Learning have led to unprecedented breakthroughs in what machines are able to achieve. In many tasks such as in Image Classification in fact, they are now capable of even surpassing human performance. While …

Behavioral Modeling of CMOS SPADs Based on TCAD Simulations
… of objects in an image, without resorting to binocular vision or interferometry techniques. They can also estimate light intensities and therefore capture 2D images based on counting pulses. For its many applications, there has been an interest in developing models from these devices in recent …

Growth factors in extraocular muscles: effects on contractile properties
… development of normal neurovisual circuits and binocular vision. In this dissertation, I examined the effects of three growth factors, IGF1 (Insulin-like Growth Factor 1), CT1 (Cardiotrophin 1), and GDNF (Glial-cell line derived neurotrophic factor), on contractile properties of extraocular …

Multidimensional Approach to Comparative Avian Visual Systems
… for food at steep angles had relatively wide binocular fields with a high degree of eye movement right <em>above</em> their short bills, whereas species that searched for food at shallower angles had narrower binocular fields with a high degree of eye movement <em>below</em> their bills. Eye …

Neuronal Diversification Within the Retina: Generation of Crossed and Uncrossed Retinal Ganglion Cells
… chiasm midline is key to the establishment of binocular vision in higher vertebrates. In the visual system of binocular animals, the ipsilaterally and contralaterally projecting retinal ganglion cells are distinguished by the laterality of their axonal projections. Specific axon guidance …

A quantitative analysis of eye movement characteristics during the cover test
… test results and the outcome of other tests of binocular function. For the investigations described in this thesis, apparatus was developed to provide precise measurements of eye movements during a computer-controlled cover test, with subjects fixating a distant (3.4m) and near (0.4m) target. In …

The functional impact of amblyopia and its associated conditions : an investigation of the potential disability associated with amblyopia and its associated conditions.
In the past decade, considerable attention has been paid to examination of the impact of amblyopia, and strabismus, upon the lives of the individuals. Although an extensive amount of literature exists regarding amblyopia and its associated visual defects, little is known about the contribution of …

THE FUNCTIONAL ROLES OF THE MOTION PERCEPTION SYSTEMS
… about motion in the form of the changes in binocular disparity over time that result from motion. This dissertation concerns the results of experimental work to determine the functional differences between the systems that utilize these sources of information. In the context of perception of …

Visual dysfunction : a contributing factor in memory deficits, and therefore learning difficulties?
… paediatric optometry tests, and in school vision screening. Eye exercises increase the range of binocular fields of vision by employing stereopsis glasses and red/green slides. Central vision loss was uncovered when students reported words, seen by only the right eye, "disappear" or "switch …
