3D printed realistic finger vein phantoms
Luuk Spreeuwers, Rasmus van der Grift, Pesigrihastamadya Normakristagaluh
Finger vein pattern recognition is an emerging biometric with a good resistance to presentation attacks and low error rates. One problem is that it is hard to obtain ground truth f…
Vulnerability of 3D Face Recognition Systems to Morphing Attacks
Sanjeet Vardam, Luuk Spreeuwers
In recent years face recognition systems have been brought to the mainstream due to development in hardware and software. Consistent efforts are being made to make them better and…
Worst-Case Morphs: a Theoretical and a Practical Approach
Una M. Kelly, Raymond Veldhuis, Luuk Spreeuwers
Face Recognition (FR) systems have been shown to be vulnerable to morphing attacks. We examine exactly how challenging morphs can become. By showing a worst-case construction in th…
A survey of face recognition techniques under occlusion
Dan Zeng, Raymond Veldhuis, Luuk Spreeuwers
The limited capacity to recognize faces under occlusions is a long-standing problem that presents a unique challenge for face recognition systems and even for humans. The problem r…
Morphing Attack Detection -- Database, Evaluation Platform and Benchmarking
Kiran Raja, Matteo Ferrara, Annalisa Franco +18
Morphing attacks have posed a severe threat to Face Recognition System (FRS). Despite the number of advancements reported in recent works, we note serious open issues such as indep…
A Layer-Based Sequential Framework for Scene Generation with GANs
Mehmet Ozgur Turkoglu, William Thong, Luuk Spreeuwers +1
The visual world we sense, interpret and interact everyday is a complex composition of interleaved physical entities. Therefore, it is a very challenging task to generate vivid sce…
Predicting Face Recognition Performance Using Image Quality
Abhishek Dutta, Raymond Veldhuis, Luuk Spreeuwers
This paper proposes a data driven model to predict the performance of a face recognition system based on image quality features. We model the relationship between image quality fea…
Can Facial Uniqueness be Inferred from Impostor Scores?
Abhishek Dutta, Raymond Veldhuis, Luuk Spreeuwers
In Biometrics, facial uniqueness is commonly inferred from impostor similarity scores. In this paper, we show that such uniqueness measures are highly unstable in the presence of i…
