A Reusable Dynamic Framework for Cognitive Vision Systems

To comply with all these requirements two measures are proposed. The underlaying software concept is founded on a component based approach [2], which is faster than classical agent systems to guarantee reactivity and enables easier distribution than conventional object oriented approaches whose scalability ends at the one computer border. To fulfil all of the above requirements the ”Service Principle” is introduced, which is derived from the CORBAservices ([8]). It is based on a ”Yellow Pages” dynamic look-up directory that makes it possible to select on-line the best available service according to a formalised performance characterisation. The resulting architecture is therefore dynamically adapted to suit optimally the current required tasks and the changing environment. Section 2 presents details and the framework test environment and a first experimental evaluation are presented in Section 3
