Modelling image quality for automotive display technologies
… form their image quality rating by weighting the visual attributes they perceive. Visual algorithms, which can be investigated via psychometric scaling, link visual attributes to the underlying physical image parameters which are typically measure by physical instruments. The visual attributes …

A psychophysical investigation of human visual perceptual memory. A study of the retention of colour, spatial frequency and motion visual information by human visual short term memory mechanisms.
The aim of this thesis was to investigate how visual information is organised in perceptual short term memory, with special interest in colour, spatial frequency and velocity. Previous studies of VSTM have indicated the existence of specific memory mechanisms for visual attributes such as …

Identity in the Late Woodland Northeast: interpreting communities of practice from paste composition at the Thomas/Luckey and the Losey 3 sites
… with pXRF. While pottery types are based on visual attributes, pXRF looks at elemental composition. Decoration is mimicable, but paste is not; paste accurately illustrates a vessel’s origin. Cultural groups are not static entities, and internal development or outgroup interaction indicates …

Selected skeletal alteration to improve beef tenderness
… The effect of this cut upon yield grade, sensory attributes and tenderness of Longissimus steaks was determined. The treatment caused no differences (P>0.05) in yield grade or in CIE L* a* b* values and oxymyoglobin, reduced myoglobin and metmyoglobin values measured on samples at the treatment …

Generalization of deep neural networks to unseen attribute combinations
Visual understanding results from a combined understanding of primitive visual attributes such as color, texture, and shape. This allows humans and other primates to generalize their understanding of objects to new combinations of attributes. For instance, one can understand that a pink elephant is …

An exploratory content analysis of comments and thumbnails of YouTube mukbang videos using computational methods
… while they watch the video. Additionally, the visual attributes of the video thumbnails are examined to explore the visual characteristics of popular Mukbang videos. The results indicate that the dominant sentiment and emotion expressed by the people were 'positive' and 'happiness'. …

Learning New Dimensions of Human Visual Similarity using Synthetic Data
… analyze how our metric is affected by different visual attributes, and find that it focuses heavily on foreground objects and semantic content while also being sensitive to color and layout. Notably, despite being trained on synthetic data, our metric generalizes to real images, giving strong …

The Relationship Between Vision and Athletic Performance
… that a relationship exists between a particular visual attribute and a specific athletic skill, it would help establish the utility for using vision enhancement exercises to improve athletic performance. In the present study, four NCAA Division I athletic teams were tested on a battery of visual …

EFFECTS OF ABSTRACT VERSUS CONCRETE VISUAL REPRESENTATIONS IN AN INSTRUCTIONAL SIMULATION ON STUDENTS' DECLARATIVE KNOWLEDGE, LEARNING TRANSFER, AND PERCEPTIONS OF THE SIMULATION
… most effectively based on the simulations' visual attributes. One of the design principles that play an important part in the simulation design process is the visual representation of on-screen objects used to describe science concepts or principles. The purpose of this study was to …

Question of Bias: A Content Analysis of the Visual Coverage of the 2004 Presidential Campaign
… in the 2004 election as evidenced by their visual coverage. Using content analysis, all the visual depictions of candidates George W. Bush and John Kerry were analyzed for 10 visual attributes to determine whether one had received better pictorial treatment. This study asked if the …

Valuing design and designing value : the financial impact of daylight and views in office building real estate
… Specifically, I measure the premium of two visual attributes--daylight and views--in office spaces in the borough of Manhattan in New York. Combining computational building performance analysis with empirical commercial rent data, I evaluate offices simultaneously as designed spaces and as …

The information design of ecological cycle network diagrams in science textbooks
… UK and Danish science textbooks (1935-2009). Visual content analysis and graphic syntax theory (Engelhardt, 2002) is applied to review the existing information categorisation in relation to four types of graphic inefectiveness: 1) implicit nodes, 2) imprecise relative spatial positioning of …

Designing representational architectures in recognition
… composites of objects. This thesis introduces visual attributes and shows how the attribute-based recognition can reason about unfamiliar objects. The attribute-based recognition also allows description of objects, the reporting of unusual properties of familiar objects, and learning about …

The Representation Of Numerosity In The Human Brain And Machines
… numerosity is inherently linked with other visual characteristics of sets (such as larger sets often occupy more space or are more densely spaced), making it challenging to determine the extent to which the observed response to numerosity is distinct from the response to other visual …

Reduced global processing bias in people with a history of mild traumatic brain injury: Grass everywhere and not a field in sight
… integrate local information (i.e., multiple visual attributes) into the percept of a single global shape. The aim of this thesis was to investigate whether people with a history of mTBI exhibit a reduced ability to integrate local information into meaningful context. Chapter 2 investigated …

The Analysis of Community Health Centers in terms of Spatial Configuration, Spatial Allocation, and Organizational Constructs
… and accessibility analysis, spatial and visual attributes include connectivity, and integration is the key space. We identify several basic spatial features of organizational structures and use them for analyzing the clinic's layouts in CHCs. We show different spatial approaches used by …

Correlating Visual Speaker Gestures with Measures of Audience Engagement to Aid Video Browsing
… we are able to derive hand motion-based gesture attributes such as velocity, direction change and extremal pose. In ground-truth studies, we manually annotate and analyze the gestures of two instructors, each in a 75-minute computer science lecture using a 14-bit pose vector. We observe …
