Color Image Edge Detection and Segmentation: A Comparison of the Vector Angle and the Euclidean Distance Color Similarity Measures
(University of Waterloo, 1999)This work is based on Shafer's Dichromatic Reflection Model as applied to color image formation. The color spaces RGB, XYZ, CIELAB, CIELUV, rgb, l1l2l3, and the new h1h2h3 color space are discussed from this perspective. ... -
A Predictive Control Method for Human Upper-Limb Motion: Graph-Theoretic Modelling, Dynamic Optimization, and Experimental Investigations
(University of Waterloo, 2000)Optimal control methods are applied to mechanical models in order to predict the control strategies in human arm movements. Optimality criteria are used to determine unique controls for a biomechanical model of the human ... -
Understanding and Improving Undergraduate Engineering Education
(University of Waterloo, 2001)This thesis seeks to understand the past and present state of engineering education and to plot a course for its future evolution. This research is limited to engineering education as it has taken place in North American ... -
Modelling Hysteresis in the Bending of Fabrics
(University of Waterloo, 2002)This thesis presents a model of fabric bending hysteresis. The hysteresis model is designed to reproduce the fabric bending measurements taken by the Kawabata Evaluation System (KES) and the model parameters can be derived ... -
Evolutionary Design for Computational Visual Attention
(University of Waterloo, 2003)A new framework for simulating the visual attention system in primates is introduced. The proposed architecture is an abstraction of existing approaches influenced by the work of Koch and Ullman, and Tompa. Each stage ... -
Modeling Continuous Emotional Appraisals of Music Using System Identification
(University of Waterloo, 2004)The goal of this project is to apply system identification techniques to model people's perception of emotion in music as a function of time. Emotional appraisals of six selections of classical music are measured from ... -
Multi-resolution Image Segmentation using Geometric Active Contours
(University of Waterloo, 2004)Image segmentation is an important step in image processing, with many applications such as pattern recognition, object detection, and medical image analysis. It is a technique that separates objects of interests from ... -
Determinants of Increased Energy Cost in Prosthetic Gait
(University of Waterloo, 2004)The physiological energy requirements of prosthetic gait in lower-limb amputees have been observed to be significantly greater than those for able-bodied subjects. However, existing models of energy flow in walking have ... -
Unsupervised Clustering and Automatic Language Model Generation for ASR
(University of Waterloo, 2004)The goal of an automatic speech recognition system is to enable the computer in understanding human speech and act accordingly. In order to realize this goal, language modeling plays an important role. It works as a ... -
Reinforcement Learning for Parameter Control of Image-Based Applications
(University of Waterloo, 2004)The significant amount of data contained in digital images present barriers to methods of learning from the information they hold. Noise and the subjectivity of image evaluation further complicate such automated processes. ... -
Preserving Texture Boundaries for SAR Sea Ice Segmentation
(University of Waterloo, 2004)Texture analysis has been used extensively in the computer-assisted interpretation of SAR sea ice imagery. Provision of maps which distinguish relevant ice types is significant for monitoring global warming and ship ... -
Dynamic Model of a Piano Action Mechanism
(University of Waterloo, 2004)While some attempts have been made to model the behaviour of the grand piano action (the mechanism that translates a key press into a hammer striking a string), most researchers have reduced the system to a simple model ... -
E-Intelligence Form Design and Data Preprocessing in Health Care
(University of Waterloo, 2004)Clinical data systems continue to grow as a result of the proliferation of features that are collected and stored. Demands for accurate and well-organized clinical data have intensified due to the increased focus on ... -
Application of Data mining in Medical Applications
(University of Waterloo, 2004)Abstract Data mining is a relatively new field of research whose major objective is to acquire knowledge from large amounts of data. In medical and health care areas, due to regulations and due to the availability ... -
Multiple Agent Architecture for a Multiple Robot System
(University of Waterloo, 2005)Controlling systems with multiple robots is quickly becoming the next large hurdle that must be overcome for groups of robots to successfully function as a team. An agent oriented approach for this problem is presented ... -
Visual Sensitivity of Dynamic Graphical Displays
(University of Waterloo, 2005)Advanced display design, such as Ecological Interface Design (EID), makes extensive use of complex graphical objects. Research has shown that by following EID methodologies, supervisory operators have better performance ... -
Average Cell Orientation, Eccentricity and Size Estimated from Tissue Images
(University of Waterloo, 2005)Five image processing algorithms are proposed to measure the average orientation, eccentricity and size of cells in images of biological tissue. These properties, which can be embodied by an elliptical 'composite cell', ... -
Towards a Versatile System for the Visual Recognition of Surface Defects
(University of Waterloo, 2005)Automated visual inspection is an emerging multi-disciplinary field with many challenges; it combines different aspects of computer vision, pattern recognition, automation, and control systems. There does not exist a ... -
The Development of System Identification Approaches for Complex Haptic Devices and Modelling Virtual Effects Using Fuzzy Logic
(University of Waterloo, 2005)Haptic applications often employ devices with many degrees of freedom in order to allow the user to have natural movement during human-machine interaction. From the development point of view, the complexity in ... -
Automatically Measuring Neuromuscular Jitter
(University of Waterloo, 2005)The analysis of electromyographic (EMG) signals detected during muscle contraction provides important information to aid in the diagnosis and characterization of neuromuscular disorders. One important analysis measures ...
