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. ... -
Secure contactless mobile financial services with near field communication
Poroye, Adeola Oluwaseyi (University of the Western Cape, 2011)This thesis presents the results from work with three prototypes that use Near Field Communication technology to provide secure contactless mobile nancial services on mobile phones. -
SIP-based content development for wireless mobile devices with delay constraints
Lakay, Elthea Trevolee (University of the Western Cape, 2006)SIP is receiving much attention these days and it seems to be the most promising candidate as a signaling protocol for the current and future IP telephony services. Realizing this, there is the obvious need to provide a ... -
SIP-based location service provision
Wu, YanHao (University of the Western Cape, 2005)Location-based service (LBS) is a geographical location-related service that provides highly personalized services for users. It is a platform for network operators to provide new and innovative ways of increasing profits ... -
Situation-aware routing for wireless mesh networks with mobile nodes
Kobo, Hlabishi (University of the Western Cape, 2012)This thesis demonstrates that a situation-aware algorithm improves quality of service on small mesh networks running BATMAN-adv with some mobile nodes. BATMAN-adv is a proactive mesh routing protocol that counts beacons ... -
Social and technical issues of IP-based multi-modal semi-synchronous communication: rural telehealth communication in South Africa
Vuza, Xolisa (University of the Western Cape, 2005)Most rural areas of developing countries are faced with problems like shortage of doctors in hospitals, illiteracy and poor power supply. Because of these issues, Information and Communication Technology (ICT) is often ... -
South African sign language recognition using feature vectors and Hidden Markov Models
Naidoo, Nathan Lyle (University of the Western Cape, 2010)This thesis presents a system for performing whole gesture recognition for South African Sign Language. The system uses feature vectors combined with Hidden Markov models. In order to constuct a feature vector, dynamic ... -
Synergistic use of promoter prediction algorithms: a choice of small training dataset?
Oppon, Ekow CruickShank (University of the Western Cape, 2000)Promoter detection, especially in prokaryotes, has always been an uphill task and may remain so, because of the many varieties of sigma factors employed by various organisms in transcription. The situation is made more ... -
A technique for the evaluation of free and open source e-learning systems
Sanga, Camilius (University of the Western Cape, 2010)Evaluating software is a universal and complex problem. The question is: how should software be selected and adopted, or rather, which of the software packages is the most suitable for a specific environment? Extensive ... -
Upper body pose recognition and estimation towards the translation of South African sign language
Achmed, Imran (University of the Western Cape, 2011)Recognising and estimating gestures is a fundamental aspect towards translating from a sign language to a spoken language. It is a challenging problem and at the same time, a growing phenomenon in Computer Vision. This ... -
The use of mobile phones as service-delivery devices in sign language machine translation system
Ghaziasgar, Mehrdad (University of the Western Cape, 2010)This thesis investigates the use of mobile phones as service-delivery devices in a sign language machine translation system. Four sign language visualization methods were evaluated on mobile phones. Three of the methods ... -
Video annotation wiki for South African sign language
Adam, Jameel (University of the Western Cape, 2011)The SASL project at the University of the Western Cape aims at developing a fully automated translation system between English and South African Sign Language (SASL). Three important aspects of this system require SASL ... -
Virtual human modelling and animation for real-time sign language visualisation
Van Wyk, Desmond Eustin (University of the Western Cape, 2008)This thesis investigates the modelling and animation of virtual humans for real-time sign language visualisation. Sign languages are fully developed natural languages used by Deaf communities all over the world. These ... -
Visualization of microprocessor execution in computer architecture courses: a case study at Kabul University
Hedayati, Mohammad Hadi (University of the Western Cape, 2010)Computer architecture and assembly language programming microprocessor execution are basic courses taught in every computer science department. Generally, however, students have difficulties in mastering many of the concepts ...
