Image Analysis in Astronomy for very large vision machine

It is developed a very complex system (hardware/software) to detect luminosity variations connected with the discovery of new planets outside the Solar System. Traditional imaging approaches are very demanding in terms of computing time; then, the implementation of an automatic vision and decision software architecture is presented. It allows to perform an on-line discrimination of interesting events by using two levels of triggers. A fundamental challenge was to work with very large CCD camera (even 16k*16k pixels) in line with very large telescopes. Then, the architecture can use a distributed parallel network system based on a maximum of 256 standard workstations.
