    • Color Image Edge Detection and Segmentation: A Comparison of the Vector Angle and the Euclidean Distance Color Similarity Measures 

      Wesolkowski, Slawomir Bogumil (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 

      Seth, Ajay (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 

      Foster, Jason (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 

      Lahey, Timothy (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 

      Bruce, Neil (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 

      Korhonen, Mark (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 ...
    • Reinforcement Learning for Parameter Control of Image-Based Applications 

      Taylor, Graham (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. ...
    • Multi-resolution Image Segmentation using Geometric Active Contours 

      Tsang, Po-Yan (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 ...
    • Preserving Texture Boundaries for SAR Sea Ice Segmentation 

      Jobanputra, Rishi (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 ...
    • Unsupervised Clustering and Automatic Language Model Generation for ASR 

      Podder, Sushil (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 ...
    • Determinants of Increased Energy Cost in Prosthetic Gait 

      Peasgood, Michael (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 ...
    • E-Intelligence Form Design and Data Preprocessing in Health Care 

      Pedarla, Padmaja (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 ...
    • Dynamic Model of a Piano Action Mechanism 

      Hirschkorn, Martin C. (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 ...
    • Application of Data mining in Medical Applications 

      Eapen, Arun George (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 ...
    • Towards a Versatile System for the Visual Recognition of Surface Defects 

      Koprnicky, Miroslav (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 ...
    • Visual Sensitivity of Dynamic Graphical Displays 

      Jessa, Munira (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 ...
    • Transparent Decision Support Using Statistical Evidence 

      Hamilton-Wright, Andrew (University of Waterloo, 2005)
      An automatically trained, statistically based, fuzzy inference system that functions as a classifier is produced. The hybrid system is designed specifically to be used as a decision support system. This hybrid system ...
    • Cleanup Memory in Biologically Plausible Neural Networks 

      Singh, Raymon (University of Waterloo, 2005)
      During the past decade, a new class of knowledge representation has emerged known as structured distributed representation (SDR). A number of schemes for encoding and manipulating such representations have been developed; ...
    • Average Cell Orientation, Eccentricity and Size Estimated from Tissue Images 

      Iles, Peter (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', ...
    • Multiple Agent Architecture for a Multiple Robot System 

      Gruneir, Bram (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 ...
