Articulated structure from motion
Scheffler, Carl (University of the Western Cape, 2004)The structure from motion (SfM) problem is that of determining 3-dimensional (3D) information of a scene from sequences of 2-dimensional (2D) images [59]. This information consists of object shape and motion and relative ... -
Browser-based and mobile video communication alternatives for Deaf people
Wang, Yuanyuan (University of the Western Cape, 2011)This thesis offers some prototypes to provide browser-based and mobile video communication services for Deaf people and evaluates these prototypes. The aim of this research is to identify an acceptable video communication ... -
Chereme-based recognition of isolated, dynamic gestures from South African sign language with Hidden Markov Models
Rajah, Christopher (University of the Western Cape, 2006)Much work has been done in building systems that can recognize gestures, e.g. as a component of sign language recognition systems. These systems typically use whole gestures as the smallest unit for recognition. Although ... -
The Complexity of Splay Trees and Skip Lists
Sayed, Hassan Adelyar. (University of the Western Cape, 2008)Our main results are that splay trees are faster for sorted insertion, where AVL trees are faster for random insertion. For searching, skip lists are faster than single class top-down splay trees, but two-class and multi-class ... -
Data mining, fraud detection and mobile telecommunications: call pattern analysis with unsupervised neural networks
Abidogun, Olusola Adeniyi (University of the Western Cape, 2005)Huge amounts of data are being collected as a result of the increased use of mobile telecommunications. Insight into information and knowledge derived from these databases can give operators a competitive edge in terms of ... -
The efficacy of the Eigenvector approach to South African sign language identification
Segers, Vaughn Mackman (University of the Western Cape, 2010)The communication barriers between deaf and hearing society mean that interaction between these communities is kept to a minimum. The South African Sign Language research group, Integration of Signed and Verbal Communication: ... -
Ellection markup language (EML) based tele-voting system
Gong, XiangQi (University of the Western Cape, 2009)Elections are one of the most fundamental activities of a democratic society. As is the case in any other aspect of life, developments in technology have resulted changes in the voting procedure from using the traditional ... -
Guaranteed delivery of multimodal semi-synchronous IP-based communication.
Julius, Elroy Peter (University of the Western Cape, 2005)A semi-synchronous environment consists of a combination of synchronous and asynchronous transport media used to transport messages from source to destination. This thesis explores an empirical solution for guaranteeing ... -
An investigation into the appropriateness of using agile processes to build an educational management information system
Sammadyar, Abdul Wahid (University of the Western Cape, 2010)Since there was a need for an Educational Management Information System (EMIS) in the Ministry of Education in Afghanistan, we designed and implemented a prototype for use in the ministry and investigated the appropriateness ... -
KernTune: self-tuning Linux kernel performance using support vector machines
Yi, Long (University of the Western Cape, 2006)Self-tuning has been an elusive goal for operating systems and is becoming a pressing issue for modern operating systems. Well-trained system administrators are able to tune an operating system to achieve better system ... -
Metric of trust for mobile ad hoc networks using source routing algorithms
Umuhoza, Denise (University of the Western Cape, 2006)This thesis proposed and presented technical details of new probabilistic metrics of trust in the links wireless ad hoc networks for unobservable communications. In covert communication networks, only the end nodes are ... -
Mobile presentations with interactive chat for m-Learning
Wanyonyi, David Wafula (University of the Western Cape, 2010)Using presentations in an m-Learning environment enables delivery of rich content to a mobile phone learner. This study investigated how to prepare and stream presentations from a desktop computer to a mobile phone in ... -
Models and applications of wireless networks in rural environments
Li, Yang (University of the Western Cape, 2005)With the unprecedented growth of the communication industry that the world is experiencing, the demand from rural inhabitants for high quality communications at an economically affordable cost is growing. However, rural ... -
Remote surveillance and face tracking with mobile phones (smart eyes)
Da Silva, Sandro Cahanda Marinho (University of the Western Cape, 2005)This thesis addresses analysis, evaluation and simulation of low complexity face detection algorithms and tracking that could be used on mobile phones. Network access control using face recognition increases the user-friendliness ... -
Rendering an avatar from sign writing notation for sign language animation
Moemedi, Kgatlhego Aretha (University of the Western Cape, 2010)This thesis presents an approach for automatically generating signing animations from a sign language notation. An avatar endowed with expressive gestures, as subtle as changes in facial expression, is used to render the ... -
Robust recognition of facial expressions on noise degraded facial images
Sheikh, Munaf (University of the Western Cape, 2011)We investigate the use of noise degraded facial images in the application of facial expression recognition. In particular, we trained Gabor+SVMclassifiers to recognize facial expressions images with various types of noise. ... -
