  1. 11. Minutiae Extraction from Fingerprint with Neural Network and Minutiae based Fingerprint Verification

    Magister-uppsats, Blekinge Tekniska Högskola/Avdelningen för signalbehandling

    Författare :Josef Ström Bartunek; [2004]
    Nyckelord :Biometrics; Fingerprints; Neural Networks; Binarization; Skeletonization; Point Pattern Matching;

    Sammanfattning : Human fingerprints are rich in details called minutiae, which can be used as identification marks for fingerprint verification. The goal of this thesis is to develop a complete system for fingerprint verification through extracting and matching minutiae. LÄS MER

  3. 12. Evaluation of biometric security systems against artificial fingers

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Johan Blommé; [2003]
    Nyckelord :Informationsteknik; biometric; artificial fingers; fingerprint scanners; minutiae; pattern matching; intrusion methods; normalization; binarization; direction field analysis; thinning algorithms; Informationsteknik;

    Sammanfattning : Verification of users’ identities are normally carried out via PIN-codes or ID- cards. Biometric identification, identification of unique body features, offers an alternative solution to these methods. Fingerprint scanning is the most common biometric identification method used today.

  4. 13. Methods for Locating Distinct Features in Fingerprint Images

    Uppsats för yrkesexamina på grundnivå, Institutionen för teknik och naturvetenskap

    Författare :Jonas Nelson; [2002]
    Nyckelord :Datorteknik; fingerprint recognition; feature extraction; biometrics; pattern recognition; template correlation; circular sampling; Datorteknik;

    Sammanfattning : With the advance of the modern information society, the importance of reliable identity authentication has increased dramatically. Using biometrics as a means for verifying the identity of a person increases both the security and the convenience of the systems. LÄS MER

  5. 14. Analys av fingeravtryck

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Marcus Henriksson; [2002]
    Nyckelord :Datorteknik; fingeravtryck; minutiae; matching; singularitetspunkter; riktningsfält; bildbehandling; Datorteknik;

    Sammanfattning : This report describes a system for verification of fingerprints against a previous created template. It describes how and why a fingerprint image must be processed before it can be used to either identify or verify a person. The method is based on special features of a fingerprint, called minutiae points. LÄS MER
