Advanced Image Quality Assessment for Hand- and Fingervein Biometrics
Simon Kirchgasser, Christof Kauba, Georg Wimmer +1
Natural Scene Statistics commonly used in non-reference image quality measures and a deep learning based quality assessment approach are proposed as biometric quality indicators fo…
Extensive Threat Analysis of Vein Attack Databases and Attack Detection by Fusion of Comparison Scores
Johannes Schuiki, Michael Linortner, Georg Wimmer +1
The last decade has brought forward many great contributions regarding presentation attack detection for the domain of finger and hand vein biometrics. Among those contributions, o…
Two-stage CNN-based wood log recognition
Georg Wimmer, Rudolf Schraml, Heinz Hofbauer +2
The proof of origin of logs is becoming increasingly important. In the context of Industry 4.0 and to combat illegal logging there is an increasing motivation to track each individ…
Demographic Bias: A Challenge for Fingervein Recognition Systems?
P. Drozdowski, B. Prommegger, G. Wimmer +4
Recently, concerns regarding potential biases in the underlying algorithms of many automated systems (including biometrics) have been raised. In this context, a biased algorithm pr…
