Simulation of Print-Scan Transformations for Face Images based on Conditional Adversarial Networks
BIOSIG 2020 - Proceedings of the 19th International Conference of the Biometrics Special Interest Group
In many countries, printing and scanning of face images is frequently performed as part of the issuance process of electronic travel documents, e.g., ePassports. Image alterations induced by such print-scan transformations may negatively effect the performance of various biometric subsystems, in particular image manipulation ...
Impact of Doppelgängers on Face Recognition: Database and Evaluation
BIOSIG 2021 - Proceedings of the 20th International Conference of the Biometrics Special Interest Group
Look-alikes, a.k.a. doppelgängers, increase the probability of false matches in a facial recognition system, in contrast to random face image pairs selected for non-mated comparison trials. In order to analyse and improve the robustness of automated face recognition, datasets of doppelgänger face image pairs are needed. ...
