Conventional wisdom would suggest to the fact that relatively poor countries are unlikely to host a “high-technology” sector. This paper examines an unusual phenomenon of industrial organization in an African setting; the emergence of a small and medium enterprise (SMEs) information technology hardware cluster in a very late industrializing country, Nigeria. The evolution of the Otigba Computer...

In this paper we propose a novel algorithm to estimate motion parameters from a single blurred image, exploiting geometrical relations between image intensities at pixels of a region that contains a corner. Corners are significant both for scene and motion understanding since they permit a univocal interpretation of motion parameters. Motion parameters are estimated locally in image regions, wi...

We describe a new method for detecting features on a marked RoboCup field. We implemented the framework for robots with omnidirectional vision, but the method can be easily adapted to other systems. The focus is on the recognition of the center circle and four different corners occurring in the penalty area. Our constructive approach differs from previous methods, in that we aim to detect a who...
