  MEDEA is a software architecture to detect luminosity variations connected
with the discovery of new planet outside the Solar System. Taking into account
the enormous number of stars to monitor for our aim traditional approaches are
very demanding in terms of computing time; here, the implementation of an
automatic vision and decision system, which allows to perform an on-line
discrimination of possible events by using two levels of trigger and a
quasi-on-line data analysis, is presented. MEDEA becomes very profitable when
dealing with large or deep surveys and provides to obtain soon results with its
powerful data analysis tools.
