Abstract :
The problem considered in this paper is the implementation of motion-detection on distributed-memory MIMD machines. The solution here proposed is based on pyramidal algorithms that, by iteratively discarding uninteresting details, allow to focus on the moving parts of an image stream. Different parallelisation methodologies have been evaluated and the most promising ones have been implemented on a Transputer-based parallel machine. Experimental results are here presented and compared with the theoretical ones
