Upper body pose recognition and estimation towards the translation of South African sign language
(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 ... -
Video annotation wiki for South African sign language
(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 ... -
Synergistic use of promoter prediction algorithms: a choice of small training dataset?
(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 ... -
An investigation into the appropriateness of using agile processes to build an educational management information system
(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 ... -
Chereme-based recognition of isolated, dynamic gestures from South African sign language with Hidden Markov Models
(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 ... -
SIP-based content development for wireless mobile devices with delay constraints
(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 ... -
Metric of trust for mobile ad hoc networks using source routing algorithms
(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 ... -
Articulated structure from motion
(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 ... -
Social and technical issues of IP-based multi-modal semi-synchronous communication: rural telehealth communication in South Africa
(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 ... -
Mobile presentations with interactive chat for m-Learning
(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 ... -
Browser-based and mobile video communication alternatives for Deaf people
(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 ... -
Secure contactless mobile financial services with near field communication
(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. -
Ellection markup language (EML) based tele-voting system
(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 ... -
Remote surveillance and face tracking with mobile phones (smart eyes)
(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 ... -
Models and applications of wireless networks in rural environments
(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 ... -
Visualization of microprocessor execution in computer architecture courses: a case study at Kabul University
(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 ... -
Data mining, fraud detection and mobile telecommunications: call pattern analysis with unsupervised neural networks
(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 ... -
Guaranteed delivery of multimodal semi-synchronous IP-based communication.
(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 ... -
