Single Morphing Attack Detection using Feature Selection and Visualisation based on Mutual Information
Juan Tapia, Christoph Busch
Face morphing attack detection is a challenging task. Automatic classification methods and manual inspection are realised in automatic border control gates to detect morphing attac…
Feature Fusion Methods for Indexing and Retrieval of Biometric Data: Application to Face Recognition with Privacy Protection
Pawel Drozdowski, Fabian Stockhardt, Christian Rathgeb +2
Computationally efficient, accurate, and privacy-preserving data storage and retrieval are among the key challenges faced by practical deployments of biometric identification syste…
Synthetic Periocular Iris PAI from a Small Set of Near-Infrared-Images
Jose Maureira, Juan Tapia, Claudia Arellano +1
Biometric has been increasing in relevance these days since it can be used for several applications such as access control for instance. Unfortunately, with the increased deploymen…
Semantic Segmentation of Periocular Near-Infra-Red Eye Images Under Alcohol Effects
Juan Tapia, Enrique Lopez Droguett, Andres Valenzuela +3
This paper proposes a new framework to detect, segment, and estimate the localization of the eyes from a periocular Near-Infra-Red iris image under alcohol consumption. The purpose…
Demographic Fairness in Face Identification: The Watchlist Imbalance Effect
Pawel Drozdowski, Christian Rathgeb, Christoph Busch
Recently, different researchers have found that the gallery composition of a face database can induce performance differentials to facial identification systems in which a probe im…
Iris Liveness Detection using a Cascade of Dedicated Deep Learning Networks
Juan Tapia, Sebastian Gonzalez, Christoph Busch
Iris pattern recognition has significantly improved the biometric authentication field due to its high stability and uniqueness. Such physical characteristics have played an essent…
