SynChildFace: Fine-tuning Face Recognition for Children with Synthetic Data
Franck V. Souop Kouam;Christian Rathgeb;Mathias Ibsen;Christoph Busch
2024 IEEE International Workshop on Information Forensics and Security (WIFS)
Year: 2024 | Conference Paper |
Many forensic investigations (e.g., the search for missing children or analysis of child pornographic data) require robust face recognition of children. However, face recognition systems are primarily designed for recognizing adults, and previous studies have already shown that they do not reliably recognize children. Moreover, the limited availability of public datasets and ethical as well as pri...Show More
Radial Distortion in Face Images: Detection and Impact
Wassim Kabbani;Tristan Le Pessot;Kiran Raja;Raghavendra Ramachandra;Christoph Busch
2024 IEEE International Joint Conference on Biometrics (IJCB)
Year: 2024 | Conference Paper |
Acquiring face images of sufficiently high quality is important for online ID and travel document issuance applications using face recognition systems (FRS). Low-quality, manipulated (intentionally or unintentionally), or distorted images degrade the FRS performance and facilitate documents’ misuse. Securing quality for enrolment images, especially in the unsupervised self-enrolment scenario via a...Show More

2023 IEEE International Joint Conference on Biometrics (IJCB)
Year: 2023 | Conference Paper |
Cited by: Papers (5)
This paper describes the results of the 2023 edition of the “LivDet” series of iris presentation attack detection (PAD) competitions. New elements in this fifth competition include (1) GAN-generated iris images as a category of presentation attack instruments (PAI), and (2) an evaluation of human accuracy at detecting PAI as a reference benchmark. Clarkson University and the University of Notre Da...Show More
