Mustererkennungsmethoden für die Fingerabdruckidentifizierung

The basic procedure executed by an AFIS (Automated Fingerprint Identification System) is stated. Figures of merit regarding crime countermeasures and security system applications in terms of notions from benchmark tests will be discussed. It is demonstrated how some most promising approaches of automated feature extraction as referenced in the current literature fit into the context of both the science of fingerprints an of advanced basic principles of pattern recognition. A continuation of the present paper, to be published in one of the next numbers of this journal, will be devoted to the problems of global feature selection and matching.
