    Sammanfattning : Biometric identification techniques are frequently used to improve security, e.g. in financial transactions, computer networks and secure critical locations. The purpose of biometric authentication systems is to verify an individual by her biological characteristics including those generating characterisitic behaviour. LÄS MER

  2. 2. Lip-motion biometrics for audio-visual identity recognition

    Detta är en avhandling från Göteborg : Chalmers university of technology

    Författare :Maycel Isaac Faraj; Högskolan i Halmstad.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Information technology Image analysis; TEKNIKVETENSKAP Informationsteknik Bildanalys; Biometrics; Lip motion; Audio-visual signals; Speech recognition; Speaker recognition; Digit recognition;

    Sammanfattning : Biometric recognition systems have been established as powerful security tools to prevent unknown users from entering high risk systems and areas. They are increasingly being utilized in surveillance and access management (city centers, banks, etc.) by using individuals' physical or biological characteristics. LÄS MER
