<p>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 thesis presents two approaches, an example-based and a learning-based approach, for performing integrated detection, segmentation and 3D estimation of the human upper body from a single camera view. It investigates whether an upper body pose can be estimated from a database of exemplars with labelled poses. It also investigates whether an upper body pose can be estimated using skin feature extraction, Support Vector Machines (SVM) and a 3D human body model. The example-based and learning-based approaches obtained success rates of 64% and 88%, respectively. An analysis of the two approaches have shown that, although the learning-based system generally performs better than the example-based system, both approaches are suitable to recognise and estimate upper body poses in a South African sign language recognition and translation system.</p>

This thesis developed a new markup language based on eXtensible Markup Language (XML), named as the Unified Programming Markup Language (UPML), which represents an abstraction of programming techniques of popular programming languages, and is used to store the programming semantic information of various programming languages. UPML aims to provide a general software quality analysis platform and as a gateway to translate programs between high-level programming languages. This research created and analyzed the features of UPML and concluded that UPML may have advantages over the traditional and newly appeared methods in software quality analysis and programming language translation. As the proof of concept in building such a software analysis and translation system, this research developed a PHP to UPML transformer. Execution examples showed its correctness of working in the core programming area of popular programming techniques, structure programming (SP) and object-oriented programming (OOP). The PHP implementation can be easily applied to other programming languages that support the same programming techniques. Since UPML is extensible, languages of other programming paradigms beyond the SP and OOP can be easily added. / Related work -- Analysis of programming languages and programming techniques -- Implementation of UPML -- Implementation of a PHP to UPML transformer -- Examples of execution. / Department of Computer Science
