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

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

    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

  3. 2. Automatic speaker verification on site and by telephone: methods, applications and assessment

    Författare :Håkan Melin; Björn Granström; Mats Blomberg; Josef Bigün; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; speaker recognition; speaker verification; speech technology; biometrics; access control; speech corpus; variance estimation; Information and language technology; Informations- och språkteknologi;

    Sammanfattning : Speaker verification is the biometric task of authenticating a claimed identity by means of analyzing a spoken sample of the claimant's voice. The present thesis deals with various topics related to automatic speaker verification (ASV) in the context of its commercial applications, characterized by co-operative users, user-friendly interfaces, and requirements for small amounts of enrollment and test data.

  4. 3. A cognitive ergonomic approach for user code design : from PIN-code to face

    Författare :Yan Pan; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk psykologi; Engineering Psychology;

    Sammanfattning : The overall goal the research upon which this thesis is based concerns the development of personal security coding that is superior to today's systems that use digit-based codes. In exploring alternate coding strategies, emphasis has been on identification of methods/systems that are more user-friendly. LÄS MER

  5. 4. Formal Verification of Tree Ensembles in Safety-Critical Applications

    Författare :John Törnblom; Simin Nadjm-Tehrani; Ingemar Söderquist; Joao Marques-Silva; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Formal verification; Machine learning; Tree ensembles;

    Sammanfattning : In the presence of data and computational resources, machine learning can be used to synthesize software automatically. For example, machines are now capable of learning complicated pattern recognition tasks and sophisticated decision policies, two key capabilities in autonomous cyber-physical systems. LÄS MER
