EnvId: A Metric Learning Approach for Forensic Few-Shot Identification of Unseen Environments
Denise Moussa, Germans Hirsch, Christian Riess
Audio recordings may provide important evidence in criminal investigations. One such case is the forensic association of a recorded audio to its recording location. For example, a…
Trustworthy Compression? Impact of AI-based Codecs on Biometrics for Law Enforcement
Sandra Bergmann, Denise Moussa, Christian Riess
Image-based biometrics can aid law enforcement in various aspects, for example in iris, fingerprint and soft-biometric recognition. A critical precondition for recognition is the a…
Point to the Hidden: Exposing Speech Audio Splicing via Signal Pointer Nets
Denise Moussa, Germans Hirsch, Sebastian Wankerl +1
Verifying the integrity of voice recording evidence for criminal investigations is an integral part of an audio forensic analyst's work. Here, one focus is on detecting deletion or…
Forensic License Plate Recognition with Compression-Informed Transformers
Denise Moussa, Anatol Maier, Andreas Spruck +2
Forensic license plate recognition (FLPR) remains an open challenge in legal contexts such as criminal investigations, where unreadable license plates (LPs) need to be deciphered f…
Towards Unconstrained Audio Splicing Detection and Localization with Neural Networks
Denise Moussa, Germans Hirsch, Christian Riess
Freely available and easy-to-use audio editing tools make it straightforward to perform audio splicing. Convincing forgeries can be created by combining various speech samples from…
