When Humans Judge Irises: Pupil Size Normalization as an Aid and Synthetic Irises as a Challenge
Mahsa Mitcheff, Adam Czajka
Iris recognition is a mature biometric technology offering remarkable precision and speed, and allowing for large-scale deployments to populations exceeding a billion enrolled user…
Gradient-Guided Exploration of Generative Model's Latent Space for Controlled Iris Image Augmentations
Mahsa Mitcheff, Siamul Karim Khan, Adam Czajka
Developing reliable iris recognition and presentation attack detection methods requires diverse datasets that capture realistic variations in iris features and a wide spectrum of a…
Privacy-Safe Iris Presentation Attack Detection
Mahsa Mitcheff, Patrick Tinsley, Adam Czajka
This paper proposes a framework for a privacy-safe iris presentation attack detection (PAD) method, designed solely with synthetically-generated, identity-leakage-free iris images.…
EyePreserve: Identity-Preserving Iris Synthesis
Siamul Karim Khan, Patrick Tinsley, Mahsa Mitcheff +3
Synthesis of same-identity biometric iris images, both for existing and non-existing identities, while preserving the identity across a wide range of pupil sizes, is complex due to…
Iris Liveness Detection Competition (LivDet-Iris) -- The 2023 Edition
Patrick Tinsley, Sandip Purnapatra, Mahsa Mitcheff +18
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 inclu…
