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

   Författare :Dereje Teferi Lemma; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; 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.
