- Description: Access to information through telecentres is essential for social and economical growth in rural areas of sub-Saharan Africa. While many governments have established telecentres as means of bridging the increasingly wide digital divide in rural or unserved areas, their corresponding sustainability or continual operation is in doubt due to various challenges. These challenges to information and communications technology (ICT) access has resulted in many of the rural population being unable to exploit the potential of promoting social economic development through innovative business solutions and education. In this study we evaluate the sustainability of telecentres in Zambia and South Africa and propose possible solutions to the problems that telecentres face. Strictly speaking, we focus on two telecentres; Comsol telecentre in KZN, South Africa and Kanyonyo Resource Centre in Mongu, Zambia.

Sharpening and contrast enhancement of atmospheric turbulence degraded video sequences
- Robinson, Philip, Walters, Bryn, Clarke, Willem
- Authors: Robinson, Philip , Walters, Bryn , Clarke, Willem
- Date: 2010
- Subjects: Atmospheric turbulence , Heat shimmer , Scinitillation , Terrestrial , Blind deconvolution , Illuminance , Reflectance
- Language: English
- Type: Abstract: Long range imaging systems that capture video through the atmosphere face a major problem in the form of atmospheric turbulence. This turbulence causes a phenomenon called heat shimmer which appears as a blurring and a wavering geometric distortion of the target scene which limits the effective range of the imaging system. We explore an image processing approach to mitigating the blurring effect of this distortion by using a blind deconvolution technique to sharpen the video signal and a dynamic illuminance-reflectance correction technique to improve the signal’s contrast. The algorithm is implemented on a Graphics Processing Unit to achieve near real-time performance. , Conference proceedings
