Pattern recognition and the nondeterminable affine parameter problem
(1998)
This thesis reports on the process of implementing pattern recognition systems using classification models such as artificial neural networks (ANNs) and algorithms whose theoretical foundations come from statistics. The ...
A transaction assurance framework for web services
(2007)
Trust assurances for customers of online transactions is an important, but not well implemented concept for the growth of confidence in electronic transactions. In an online world where customers do not personally know the ...
Situation recognition using soft computing techniques
(2012)
The last decades have witnessed the emergence of a large number of devices pervasively launched into our daily lives as systems producing and collecting data from a variety of information sources to provide different ...
Adapting a novel public display system for an educational context
(2010)
Universities in developing nations are viewed as gateways to global knowledge and as the source of human capital for their countries' economies (Juma, 2008). However, these universities face challenges in accessing educational ...
Improving searchability of automatically transcribed lectures through dynamic language modelling
(2012)
Recording university lectures through lecture capture systems is increasingly common. However, a single continuous audio recording is often unhelpful for users, who may wish to navigate quickly to a particular part of a ...
Large image support in digital repositories
(2010)
Many universities, libraries, government organisations and companies are implementing digital repositories to collect, preserve, administer and distribute their collections via the World Wide Web. In the process of building ...
Fast and accurate visibility preprocessing
(2003)
Currently, the standard approach to visibility preprocessing algorithms is to use a form of approximate solution, known as conservative culling. Such algorithms over-estimate the set of visible polygons. This compromise ...
An end to end solution for complex open educational resources
(2012)
The main objective of this thesis is to provide content creators and educators with a solution that simplifies the process of depositing into digital repositories. We created a desktop tool named ORchiD, Open educational ...
Distributed texture-based terrain synthesis
(2011)
Terrain synthesis is an important field of Computer Graphics that deals with the generation of 3D landscape models for use in virtual environments. The field has evolved to a stage where large and even infinite landscapes ...
Tissue segmentation of the cerebellum from MR images
(2011)
The cerebellum is known to be very susceptible to prenatal exposure to alcohol and people affected by Fetal Alcohol Spectrum Disorder (FASD) show a decrease in cerebellar volume. Unfortunately, there seems to be little ...
