  1. 1. Recognition and Evaluation by Video Synthesis Methods and Symmetry Features

    Författare :Dereje Teferi Lemma; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Biometrics; eye detection; video synthesis; liveness detection; camera calibration; damascening; Generalized Structure Tensor; symmetry codes;

    Sammanfattning : Biometrics is being increasingly utilized for person authentication. It requires little or no efforts from the user as compared to traditional non-biometric systems where the user has to memorize PIN codes and passwords or carry pass cards and keys that can be easily forgotten or lost.
