Discrete visual structures : elements of visual grammar
… a large and complex group of standardized visual signs which I call discrete visual structures. A fundamental characteristic of a discrete visual structure is its possibility to be visually represented. The relations between these structures depend primarily on their graphic organization …

Statistically learned visual representations support visual working memory
Visual statistical learning (VSL) refers to the human ability to unintentionally extract statistical information from our environment. VSL has been proposed to have wide-reaching influence on a number of aspects of cognition. However, direct evidence that statistically learned information is used …

Visual Discomfort and Visual Function: Colour and Contrast
In six studies, vision and visual discomfort were investigated in individuals who experienced migraine or reading difficulty. Contrast discrimination thresholds were measured at two pedestal contrasts (10% and 50%) in volunteers with migraine with aura (MA), without aura (MO) and controls (C).There …

Visual Politics: Visual Political Communication on Social Media
Visuals are integral part of our life, and it is also true for political communication. Political posters and advertisements are not only visible on television, the streets but everywhere on the Internet, especially on social media. It is highly unlikely to go through our Facebook newsfeed without …

Learning visual models from paired audio-visual examples
… bustle of a busy café, our days are filled with visual experiences that are accompanied by distinctive sounds. In this thesis, we show that these sounds can provide a rich training signal for learning visual models. First, we propose the task of predicting the sound that an object makes when …

Exploiting visual motion to understand our visual world
Motion is important for understanding our visual world. The human visual system relies heavily on motion perception to recognize the movement of objects, to infer the 3D geometry of a scene, and to perceive the emotions of other people. Modern computer vision systems also use motion signals …

Visual Phallacies
Roland Barthes wrote that only after removing all of the author's intentions and traces can a work of art truly be perceived by viewers fairly (Barthes). A viewer's perception of the world is influenced by his or her individual subjective history, which is the product of his or her own experiences. …

Visual memory
Visual memory supports computer vision applications by efficiently storing and retrieving spatiotemporal information. It is a unique combination of databases, spatial representation and indexing, and temporal representation and indexing. This thesis designs a visual memory architecture that meets …

Visual Descriptors: A Design Tool for Visual Impact Analysis
… effective form of computer-aided analysis of the visual impact of building development in rural areas. Its contribution is fourfold. Firstly, a conceptual model has been developed for the process of seeing in the context of visual impact analysis. Secondly, a mathematical model for a consistent …

TOWARD A VISUAL PAIDEIA: VISUAL RHETORIC IN UNDERGRADUATE WRITING PROGRAMS
… as rich and dynamic combinations of verbal, visual, and aural elements. Instruction in visual rhetoric in the writing classroom, however, has tended to focus on analysis with far less emphasis on teaching students how to produce multimodal texts. Drawing upon classical rhetorical theory, I …

Modeling the visual pathway for interactive diagnosis of visual fields
"Visual fields are an important tool for the ophthalmologist in the detection, diagnosis, and monitoring of certain diseases and maladies of the visual pathway. The aim of the present research is to build a computer system which utilizes a learning machine to develop a mathematical model of the …

Fusion of non-visual and visual sensors for human tracking
… may not be successfully tracked with merely the visual information in challenging cases such as long-term occlusion. Thus, we propose to combine information from other sensors with the surveillance cameras to persistently localize and track humans, which is becoming more promising with the …

Visual-Spatial & Visual-Motor Function in Pediatric Heart Transplant Recipients
… with resulting difficulty during tasks requiring visual-spatial and visual-motor skills. This study compares the performance of children who received a heart transplant during infancy to that of nonclinical children with no medical complications on three visual-motor measures, three visual-spatial …

The parallel nature of early visual processing in visual search
Visual search is a process that is ubiquitous in daily life. Some are relatively easy – looking for a red sock among black socks – while others are extremely difficult – looking for tumors in x-ray images. Classic theories and models of search have long assumed that these easy searches, referred to …

Visual object tracking
Visual object tracking is a critical task in many computer-vision-related applications, such as surveillance and robotics. If the tracking target is provided in the first frame of a video, the tracker will predict the location and the shape of the target in the following frames. Despite the …
