This talk will cover the iris presentation attack detection. With a backbone based on two survey papers on this topic recently co-authored by Czajka (published in ACM Computing Surveys, 2018 and in Pattern Recognition Letters, 2020), Czajka will primarily discuss the problem of recognition of unknown attack types (unseen during training), or less popular attack types (such as cadaver eyes), and will bring a few ideas of making the iris PAD algorithms more attack type-agnostic. A short summary of available iris PAD datasets, open-source iris PAD solutions, and the performance in an open-set classification regime observed in the fourth edition of LivDet-Iris competition (concluded in 2020) will be delivered.
Adam Czajka is an Assistant Professor in the Department of Computer Science and Engineering at the University of Notre Dame. His research focuses on biometrics and security, especially on human-driven methods of detecting unknown types of presentation attacks driving a biometric system into incorrect decision. In general, he is fascinated by wide spectrum of research topics in computer vision, pattern recognition and machine learning. Recently, he has been exploring the use of visual signals generated by artificial neural networks in stimulation of emotions and mental healing processes. In the classroom, he enjoys teaching graduate- and undergraduate-level Computer Vision (CSE 40535/60535/40536/60536), Biometrics (CSE 40537/60537) and Neural Networks (CSE 40868/60868) courses.
Czajka is originally from Poland. He received M.Sc. in Computer Control Systems (hons), Ph.D. in Biometrics (hons) and D.Sc. degree ("habilitation") in Computer Science, all from Warsaw University of Technology (WUT). Before coming to Notre Dame, he was the Chair and co-founder of the Biometrics and Machine Learning Laboratory in the Institute of Control and Computation Engineering at WUT, the Head of the Postgraduate Studies on Security and Biometrics, the Vice Chair of the NASK Biometrics Laboratory, and the Chair of the Polish Standardization Committee on Biometrics. He is a Senior Member of the IEEE, an active member of the EAB, an associate member of the IAI and an expert of ISO/IEC Sub-Committee 37 on Biometrics.
