Gaze selection in the real world : finding evidence for a preferential selection of eyesBirmingham, Elina 11 1900 (has links)
We have a strong intuition that people's eyes are unique, socially informative stimuli. As such, it is reasonable to propose that humans have developed a fundamental tendency to preferentially attend to eyes in the environment. The empirical evidence to support this intuition is, however, remarkably thin. Over the course of eight chapters, the present thesis considers the area of social attention, and what special role (if any) the selection of eyes has in it. Chapters 2 and 3 demonstrate that when observers are shown complex natural scenes, they look at the eyes more frequently than any other region. This selection preference is enhanced when the social content and activity in the scene is high, and when the task is to report on the attentional states in the scene. Chapters 4 and 5 establish that the bias to select eyes extends to a variety of tasks, suggesting that it may be fundamental to human social attention. In addition, Chapter 5 shows that observers who are told that they will have to remember the scenes look more often at the eyes than observers who are unaware of the forthcoming memory test; moreover this difference between groups persists to scene recognition. Chapter 6 examines whether the preference for eyes can be explained by visual saliency. It cannot. Chapter 7 compares the selection of eyes to another socially communicative cue, the arrow. The results shed light on a recent controversy in the social attention field, and indicate again that there is a fundamental bias to select the eyes. Collectively the data suggest that for typically developing adults, eyes are rich, socially communicative stimuli that are preferentially attended to relative to other stimuli in the environment.

Visual control in natural and artificial systemsYoung, Rupert January 2000 (has links)
The desire to produce artificial vision systems which behave in an intelligent, humanlike way or which can autonomously and automatically perform tasks currently only performed by humans has been a goal of Artificial Intelligence research for many decades. Until recently much of the research concentrated on extracting visual representations of objects from single, static scenes. The last decade has seen an increase in interest concerning mobile robotics for navigation, planning and autonomous control as well as for the interpretation of events in real, dynamic scenes. Presented in this thesis is research on artificial vision systems from two different, but both necessary, standpoints. One concerns low-level vision-based behaviour of object tracking based upon a naturalistic theory of perception and behaviour within living systems. The other takes a more application and engineering based approach and its goal is to address high-level scene interpretation and control of processing resources. Numerous experiments are presented to demonstrate the various issues. The two main experiments, corresponding to the two research streams, are a system which is able to fixate complex multi-coloured objects and a fully integrated vision system for predicting and following, with a mobile sensor, events in a dynamic scene.

Evaluation of wet-vacuum technique versus traditional methods for collection of biological crime scene samplesPatlak, David Julian January 2013 (has links)
Generally, biological samples are collected from crime scenes using swabbing, cutting, or taping techniques. However, these methods are limited in their abilities to recover diluted, masked, or otherwise invisible stains. Additionally, their targeted nature allows only a small portion of a larger stain to be collected at one time. In this study, a sterile wet-vacuum collection system was evaluated in its ability to collect small volume bloodstains from various substrates. Vacuuming was compared to swabbing and taping methods currently used in forensic analysis. Samples were collected from porous and nonporous surfaces; the efficacy of each collection method was evaluated with a colorimetric presumptive blood test.
To evaluate each collection method, dilutions containing from 0.25 nl to 25 μl human blood were spotted on common substrate materials, allowed to dry, and recovered. For comparison to the novel method, single-swabbing and tape-lifting techniques were performed in this study to collect samples for presumptive testing. During wet vacuum collection, stains were saturated with sterile buffer and suction was applied to the surrounding area, accumulating buffer in a collection bottle. Collected buffer was then filtered through membranes to capture cellular material, which were then presumptively tested for the presence of blood. Testing was performed with Kastle-Meyer (phenolphthalein) reagents. Each sample was photographed under consistent conditions in order to determine signal intensity.
It was shown that the wet-vacuuming technique is able to recover sufficient amounts of blood for presumptive testing from multiple substrates. This method was able to detect similar dilutions of blood as traditional techniques in samples collected from porous surfaces, but was less effective on a nonporous substrate. Presumptive test image analysis shows increased relative intensity in collections from textiles, such as denim, when using the wet-vacuum system. Considering the results of a contemporaneous DNA quantification study, it was shown that in instances where a very weak presumptive result is found, the wet-vacuum technique may be better able to collect genetic material for downstream processing than the traditional methods evaluated. This study demonstrates the potential of wet-vacuuming as a suitable alternative technique to collect adhered cellular material from substrates in forensic investigations.

New Craig County Hall -- A Scene ContainerWang, Peng 03 December 2003 (has links)
In contemporary downtown historic area renovation, conflicts between the new building and the environment always exist. To better solve the problem, a concept of Scene Container was introduced into the New Craig County Hall design, achieved by framing views from the new building towards historic scenery outside. Layered spaces with differing degrees of enclosure also help to build visual contact between new and old. / Master of Architecture
