Accelerated deconvolution of radio interferometric images using orthogonal matching pursuit and graphics hardware
(2016)
Deconvolution of native radio interferometric images constitutes a major computational component of the radio astronomy imaging process. An efficient and robust deconvolution operation is essential for reconstruction of ...
Understanding merchant adoption of m-payments in South Africa
(2016)
Despite the proliferation of mobile communication technology and smartphone adoption, a number of barriers, most notably trust and security, and the lack of critical mass, have slowed the uptake of mobile payments (m-payments). ...
Automating user privacy policy recommendations in social media
(2016)
Most Social Media Platforms (SMPs) implement privacy policies that enable users to protect their sensitive information against privacy violations. However, observations indicate that users find these privacy policies ...
Natural language interface to relational database: a simplified customization approach
(2016)
Natural language interfaces to databases (NLIDB) allow end-users with no knowledge of a formal language like SQL to query databases. One of the main open problems currently investigated is the development of NLIDB systems ...
Investigating image processing algorithms for provision of information in rock art sites using mobile devices
(2016)
The term cultural heritage spaces incorporates places, objects and practices of cultural and historical significance. Examples include the Southern African rock art heritage sites. Rock art is an archaeological term used ...
Investigating prediction modelling of academic performance for students in rural schools in Kenya
(2016)
Academic performance prediction modelling provides an opportunity for learners' probable outcomes to be known early, before they sit for final examinations. This would be particularly useful for education stakeholders to ...
An automatic marker for vector graphics drawing tasks
(2016)
In recent years, the SVG file format has grown increasingly popular, largely due to its widespread adoption as the standard image format for vector graphics on the World Wide Web. However, vector graphics predate the modern ...
Design and optimisation of a low cost Cognitive Mesh Network
(2016)
Wireless Mesh Networks (WMNs) have been touted as the most promising wireless technology in providing high-bandwidth Internet access to rural, remote and under-served areas, with relatively lower investment cost as compared ...
Procedurally generating surface detail for 3D models using voxel-based cellular automata
(2016)
Procedural generation is used extensively in the field of computer graphics to automate content generation and speed up development. One particular area often automated is the generation of additional colour and structural ...
Multitouch-based collaborative pre-visualisation for computer animation
(2016)
Computer animated pre-visualisation occurs at an early stage of visualising scenes in low-fidelity. This is a collaborative process, in which directors communicate with animators how shot sequences will occur. Producers ...
