Neural computation of depth from binocular disparity
… capable of swiftly transforming a stream of binocular two-dimensional signals into a cohesive three-dimensional percept? Many brain regions have been implicated in stereoscopic processing, but their roles remain poorly understood. This dissertation focuses on the contributions of primary and …

Perceived Depth in Virtual and Physical Environments
… and physical objects defined by motion parallax, binocular disparity, or their combination. Accuracy was remarkedly similar for both environments, but estimates were more precise when depth was defined by binocular disparity than motion parallax. A linear combination model did not adequately …

Brain stimulation reveals neural mechanisms of stereopsis
… for interaction with our environment. However, binocular disparity in natural images is often ambiguous and this makes it difficult to establish a binocular correspondence solution. In my thesis, I focus on both the challenges of this problem and solutions that the brain applies. To study brain …

Dynamical systems approach to binocular stereopsis
The extraction of depth in binocular stereopsis relies upon the ability to detect the co-occurrence of similar features in a stereo pair of images and the subsequent extraction of positional disparity. The fundamental problem of stereopsis is to achieve coordinated activity through the linkage of …

Holographic television : measuring visual performance with holographic and other 3D television technologies
… a set of findings that illuminate the value of binocular disparity, and ocular focus information that can be provided by some three-dimensional display technologies. These findings include new experimental methods, as well as results, for conducting evaluations of current and future display …

Computational and laboratory investigations of a model of blood droplet flight for forensic applications
… in at images by providing additional binocular depth cues, such as convergence and binocular disparity. In this thesis, we explore the e ects that S3D has on the player experience in an attempt to uncover design methodologies that can help game developers develop more e ective content. …

Stereoscopic depth axis interaction: A study of performance and engagement in stereoscopic 3D games.
… in at images by providing additional binocular depth cues, such as convergence and binocular disparity. In this thesis, we explore the effects that S3D has on the player experience in an attempt to uncover design methodologies that can help game developers develop more effective …

Perception and Eye Alignment Control: Do People Think the Same Way Their Brain Thinks?
… This thesis compares two distinct but related binocular disparity processing phenomena— stereoscopic depth perception and reflexive disparity vergence. Stereoscopic thresholds typically improve with increasing target contrast, but when only one eye’s target contrast increases, the stereoscopic …

THE FUNCTIONAL ROLES OF THE MOTION PERCEPTION SYSTEMS
… interocular velocity differences. Also, there is disparity-based information 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 …

Confidence and feedback in visual perceptual learning
… random-dot stereogram (ACRDS). The binocular energy model of neural responses predicts that depth from binocular disparity may be perceived in the reversed-direction when the contrast of dots are anti-correlated. Depth was mostly perceived in the correct direction for ACRDS …

Effects of depth cues on depth judgements using a field-sequential stereoscopic CRT display
… of field-sequential CRT techniques to present binocular stereoscopic images. Although it is widely believed that stereopsis provides a potent depth information cue, numerous monocular cues exist which may augment, detract from, or even supplant stereopsis. Unfortunately, few guidelines or …

Path from Photorealism to Perceptual Realism
… real-time rendering algorithm that exploits the binocular fusion mechanism of the human visual system to boost the perceived local contrast of stereoscopic displays. The method was inspired by an established model of binocular contrast fusion. To optimise the experience of binocular fusion, we …
