Multi-Modal Fingerprint Presentation Attack Detection: Evaluation On A New Dataset

1 code implementation12 Jun 2020 Leonidas Spinoulas, Hengameh Mirzaalian, Mohamed Hussein, Wael Abd-Almageed

Our evaluation compares different combination of the new sensing modalities to legacy data from one of our collections as well as the public LivDet2015 dataset, showing the superiority of the new sensing modalities in most cases.

Multispectral Biometrics System Framework: Application to Presentation Attack Detection

no code implementations12 Jun 2020 Leonidas Spinoulas, Mohamed Hussein, David Geissbühler, Joe Mathai, Oswin G. Almeida, Guillaume Clivaz, Sébastien Marcel, Wael Abd-Almageed

In this work, we present a general framework for building a biometrics system capable of capturing multispectral data from a series of sensors synchronized with active illumination sources.
