Proceedings ArticleDOI
Morphed Face Detection Based on Deep Color Residual Noise
Sushma Venkatesh,Raghavendra Ramachandra,Kiran B. Raja,Luuk Spreeuwers,Raymond N.J. Veldhuis,Christoph Busch +5 more
TL;DR: A novel approach to detect morphed face images using residual color noise using Deep Convolutional Neural Network independently on the Hue Saturation Value (HSV) color space, and then computes the residual noise.
Proceedings ArticleDOI
Classifying accelerometer data via Hidden Markov Models to authenticate people by the way they walk
Claudia Nickel,Christoph Busch +1 more
TL;DR: The results when using a more realistic data set containing walking around corners, upstairs and downstairs etc are shown and it is analyzed to which extent the biometric performance is degraded when this more demanding data set is used.
Proceedings ArticleDOI
Towards Fingerprint Presentation Attack Detection Based on Convolutional Neural Networks and Short Wave Infrared Imaging
Ruben Tolosana,Marta Gomez-Barrero,Jascha Kolberg,Aythami Morales,Christoph Busch,Javier Ortega-Garcia +5 more
TL;DR: A new fingerprint presentation attack detection method based on convolutional neural networks and multi-spectral images extracted from the finger in the short wave infrared spectrum is presented.
Proceedings ArticleDOI
