Heterogeneous Face Recognition Using Domain Invariant Units

no code implementations22 Apr 2024 Anjith George, Sebastien Marcel

Heterogeneous Face Recognition (HFR) aims to expand the applicability of Face Recognition (FR) systems to challenging scenarios, enabling the matching of face images across different domains, such as matching thermal images to visible spectra.

Fairness Index Measures to Evaluate Bias in Biometric Recognition

no code implementations19 Jun 2023 Ketan Kotwal, Sebastien Marcel

While few, existing fairness measures are based on post-decision data (such as verification accuracy) of biometric systems, we discuss how pre-decision data (score distributions) provide useful insights towards demographic fairness.
