    • Computer Vision on Web Pages: A Study of Man-Made Images 

      Cormier, Michael (University of Waterloo, 2018-08-02)
      This thesis is focused on the development of computer vision techniques for parsing web pages using an image of the rendered page as evidence, and on understanding this under-explored class of images from the perspective ...
    • Computer-Aided Diagnosis for Early Identification of Multi-Type Dementia using Deep Neural Networks 

      Alkabawi, Elham (University of Waterloo, 2017-10-24)
      With millions of people suffering from dementia worldwide, the global prevalence of this condition has a significant impact on the global economy. As well, its prevalence has a negative impact on patients’ lives and their ...
    • A Computer-Based Decision Tool for Prioritizing the Reduction of Airborne Chemical Emissions from Canadian Oil Refineries Using Estimated Health Impacts 

      Gower, Stephanie Karen (University of Waterloo, 2007-04-17)
      Petroleum refineries emit a variety of airborne substances which may be harmful to human health. HEIDI II (Health Effects Indicators Decision Index II) is a computer-based decision analysis tool which assesses airborne ...
    • Computerized and Non-Computerized Colour Vision Tests 

      Almustanyir, Ali (University of Waterloo, 2014-08-05)
      Introduction: Measuring colour discrimination of people who carry out tasks where colour is used to convey information and accurate colour judgments are essential for safe and efficient performance of the task is important ...
    • Computing a Basis for an Integer Lattice 

      Li, Haomin (University of Waterloo, 2022-12-22)
      The extended gcd problem takes as input two integers, and asks as output an integer linear combination of the integers that are equal to their gcd. The classical extended Euclidean algorithm and fast variants such as the ...
    • Computing Approximate GCRDs of Differential Polynomials 

      Haraldson, Joseph (University of Waterloo, 2015-09-21)
      We generalize the approximate greatest common divisor problem to the non-commutative, approximate Greatest Common Right Divisor (GCRD) problem of differential polynomials. Algorithms for performing arithmetic on approximate ...
    • Computing Matrix Canonical Forms of Ore Polynomials 

      Khochtali, Mohamed (University of Waterloo, 2017-05-01)
      We present algorithms to compute canonical forms of matrices of Ore polynomials while controlling intermediate expression swell. Given a square non-singular input matrix of Ore polynomials, we give an extension of the ...
    • Computing Popov Forms of Polynomial Matrices 

      Sarkar, Soumojit (University of Waterloo, 2012-01-19)
      This thesis gives a deterministic algorithm to transform a row reduced matrix to canon- ical Popov form. Given as input a row reduced matrix R over K[x], K a field, our algorithm computes the Popov form in about the same ...
    • Computing Realistic Terrains from Imprecise Elevations 

      Stroud, Graeme Robinson (University of Waterloo, 2022-04-19)
      It is ideal for triangulated terrains to have characteristics or properties that are realistic. In the imprecise terrain model, each vertex of a triangulated terrain has an imprecise eleva- tion value only known to lie ...
    • Computing sparse multiples of polynomials 

      Tilak, Hrushikesh (University of Waterloo, 2010-08-31)
      We consider the problem of finding a sparse multiple of a polynomial. Given a polynomial f ∈ F[x] of degree d over a field F, and a desired sparsity t = O(1), our goal is to determine if there exists a multiple h ∈ F[x] ...
    • Computing the Nucleolus of Matching and b-Matching Games 

      Toth, William Justin (University of Waterloo, 2021-05-21)
      In the classical weighted matching problem the optimizer is given a graph with edge weights and their goal is to find a matching which maximizes the sum of the weights of edges in the matching. It is typically assumed in ...
    • Computing the Residue Class of Partition Numbers 

      Shuldiner, Pavel (University of Waterloo, 2016-09-14)
      In 1919, Ramanujan initiated the study of congruence properties of the integer partition function $p(n)$ by showing that $$p(5n+4) \equiv 0 \mod{5}$$ and $$p(7n+5) \equiv 0 \mod{7}$$ hold for all integers $n$. These results ...
    • Computing with Multi-Row Intersection Cuts
