Abstract

Fingerprints are one of the most important biometric characteristic due to their known uniqueness and persistence properties. However, these systems suffer from distinct problems, e.g. low contrast caused by dirt or humidity on the capturing device plate or hygienic concerns. To tackle shortcomings of contact-based fingerprint recognition, contactless fingerprint recognition systems have been researched for more than a decade.
This talk presents a summary of recent advances in the research area of contactless fingerprint recognition. Starting with an overview of our recognition pipeline, the talk covers several aspects of contactless fingerprint recognition. Also, the impact of the COVID-19 pandemic on fingerprint recognition will be discussed. Biometric sample quality assessment re-training the well-know NFIQ2 algorithm for contactless fingerprints is also covered. Synthetic fingerprint generation which pave the way for new directions are presented as well, as new ideas for feature extraction and presentation attack detection in the contactless domain.
