Synthetic Fingerprints for Children Under Four: Generation and Biometric Evaluation
Faheem Ahmad, Ajan Ahmed, Mst Rumana Sumi +2
Fingerprint recognition in children under four is of interest for longitudinal identity applications, but research in this age range is constrained by the limited availability and…
Beyond ROC-AUC: Operating-Point Performance Reporting for Biometric Verification
Ajan Ahmed, Masudul H. Imtiaz
A biometric verifier is often deployed with a strict false match budget, so only a narrow, low false match rate (FMR) slice of the score range is used. A reporting standard for thi…
Classical Machine Learning Baselines for Deepfake Audio Detection on the Fake-or-Real Dataset
Faheem Ahmad, Ajan Ahmed, Masudul Imtiaz
Deep learning has enabled highly realistic synthetic speech, raising concerns about fraud, impersonation, and disinformation. Despite rapid progress in neural detectors, transparen…
Descriptor:: Extended-Length Audio Dataset for Synthetic Voice Detection and Speaker Recognition (ELAD-SVDSR)
Rahul Vijaykumar, Ajan Ahmed, John Parker +4
This paper introduces the Extended Length Audio Dataset for Synthetic Voice Detection and Speaker Recognition (ELAD SVDSR), a resource specifically designed to facilitate the creat…
A Comparative Evaluation of Deep Learning Models for Speech Enhancement in Real-World Noisy Environments
Md Jahangir Alam Khondkar, Ajan Ahmed, Stephanie Schuckers +1
Speech enhancement, particularly denoising, is vital in improving the intelligibility and quality of speech signals for real-world applications, especially in noisy environments. W…
