Fast cross-correlation based wrist vein recognition algorithm with rotation and translation compensation

Sébastien Marcel, André Anjos, Teodors Eglitis

Most of the research on vein biometrics addresses the problems of either palm or finger vein recognition with a considerably smaller emphasis on wrist vein modality. This paper paves the way to a better understanding of capabilities and challenges in the f ...

On Effectiveness of Anomaly Detection Approaches against Unseen Presentation Attacks in Face Anti-Spoofing

Sébastien Marcel, André Anjos, Amir Mohammadi

While face recognition systems got a significant boost in terms of recognition performance in recent years, they are known to be vulnerable to presentation attacks. Up to date, most of the research in the field of face anti-spoofing or presentation attack ...

On the use of client identity information for face anti-spoofing

André Anjos, Ivana Chingovska

With biometrics playing the role of a password which can not be replaced if stolen, the necessity of establishing counter- measures to biometric spoofing attacks has been recognized. Regardless of the biometric mode, the typical approach of anti-spoofing s ...
