State of the Art of Quality Assessment of Facial Images

no code implementations15 Nov 2022 Johannes Merkle, Christian Rathgeb, Benjamin Tams, Dhay-Parn Lou, André Dörsch, Pawel Drozdowski

The goal of the project "Facial Metrics for EES" is to develop, implement and publish an open source algorithm for the quality assessment of facial images (OFIQ) for face recognition, in particular for border control scenarios. 1 In order to stimulate the harmonization of the requirements and practices applied for QA for facial images, the insights gained and algorithms developed in the project will be contributed to the current (2022) revision of the ISO/IEC 29794-5 standard.

Face Beneath the Ink: Synthetic Data and Tattoo Removal with Application to Face Recognition

no code implementations10 Feb 2022 Mathias Ibsen, Christian Rathgeb, Pawel Drozdowski, Christoph Busch

Moreover, we demonstrate the feasibility of the generation by using a deep learning-based model for removing tattoos from face images.

Crowd-powered Face Manipulation Detection: Fusing Human Examiner Decisions

no code implementations31 Jan 2022 Christian Rathgeb, Robert Nichols, Mathias Ibsen, Pawel Drozdowski, Christoph Busch

To this end, various decision fusion methods are proposed incorporating the examiners' decision confidence, experience level, and their time to take a decision.

Psychophysical Evaluation of Human Performance in Detecting Digital Face Image Manipulations

no code implementations28 Jan 2022 Robert Nichols, Christian Rathgeb, Pawel Drozdowski, Christoph Busch

In recent years, increasing deployment of face recognition technology in security-critical settings, such as border control or law enforcement, has led to considerable interest in the vulnerability of face recognition systems to attacks utilising legitimate documents, which are issued on the basis of digitally manipulated face images.

Reliable Detection of Doppelgängers based on Deep Face Representations

no code implementations21 Jan 2022 Christian Rathgeb, Daniel Fischer, Pawel Drozdowski, Christoph Busch

Doppelg\"angers (or lookalikes) usually yield an increased probability of false matches in a facial recognition system, as opposed to random face image pairs selected for non-mated comparison trials.

Demographic Fairness in Face Identification: The Watchlist Imbalance Effect

no code implementations15 Jun 2021 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 image is compared against up to all stored reference images to reach a biometric decision.

Demographic Fairness in Biometric Systems: What do the Experts say?

no code implementations31 May 2021 Christian Rathgeb, Pawel Drozdowski, Naser Damer, Dinusha C. Frings, Christoph Busch

Algorithmic decision systems have frequently been labelled as "biased", "racist", "sexist", or "unfair" by numerous media outlets, organisations, and researchers.

Signal-level Fusion for Indexing and Retrieval of Facial Biometric Data

no code implementations5 Mar 2021 Pawel Drozdowski, Fabian Stockhardt, Christian Rathgeb, Christoph Busch

The growing scope, scale, and number of biometric deployments around the world emphasise the need for research into technologies facilitating efficient and reliable biometric identification queries.


Detection of Makeup Presentation Attacks based on Deep Face Representations

no code implementations9 Jun 2020 Christian Rathgeb, Pawel Drozdowski, Christoph Busch

Facial cosmetics have the ability to substantially alter the facial appearance, which can negatively affect the decisions of a face recognition.
