Neural Systems for Complex Identification Tasks: The Access Control System ZN-Face and the Alarm Identification SENECA for Steel Casting Processes

. Neural systems have become a widely used tool in many industrial and commercial applications. We report in this contribution on new applications of diagnosis and identification systems in two areas. Firstly, we present the access control system ZNFace, a product developped at the ZN, which makes automated face recognition available for commercial access control systems. Neural systems have the necessary flexibility to analyse the visual information correctly, which we perceive so easily as a person's face. ZN-Face combines high recognition rates (99 %) with fast computation (3 sec) on standard hardware components (PC). The system is integrated into an easy-to-use GUI. ZNFace is in daily operation at a large company since summer 1995. -- Secondly, we report on a neural system for industrial process diagnosis, namely alarm identification in continuous steel casting, where a neural net in combination with a fuzzy system detects dangerous "hot spot"-process faults (breakouts) from the ob..
