\textit{sweet} -- An Open Source Modular Platform for Contactless Hand Vascular Biometric Experiments

no code implementations14 Apr 2024 David Geissbühler, Sushil Bhattacharjee, Ketan Kotwal, Guillaume Clivaz, Sébastien Marcel

In this work we present a contactless vascular biometrics sensor platform named \sweet which can be used for hand vascular biometrics studies (wrist-, palm- and finger-vein) and surface features such as palmprint.

Latent Enhancing AutoEncoder for Occluded Image Classification

no code implementations10 Feb 2024 Ketan Kotwal, Tanay Deshmukh, Preeti Gopal

On the OccludedPASCAL3D+ dataset, the proposed LEARN outperforms standard classification models (VGG16 and ResNet-50) by a large margin and up to 2% over state-of-the-art methods.

EFaR 2023: Efficient Face Recognition Competition

1 code implementation8 Aug 2023 Jan Niklas Kolf, Fadi Boutros, Jurek Elliesen, Markus Theuerkauf, Naser Damer, Mohamad Alansari, Oussama Abdul Hay, Sara Alansari, Sajid Javed, Naoufel Werghi, Klemen Grm, Vitomir Štruc, Fernando Alonso-Fernandez, Kevin Hernandez Diaz, Josef Bigun, Anjith George, Christophe Ecabert, Hatef Otroshi Shahreza, Ketan Kotwal, Sébastien Marcel, Iurii Medvedev, Bo Jin, Diogo Nunes, Ahmad Hassanpour, Pankaj Khatiwada, Aafan Ahmad Toor, Bian Yang

To drive further development of efficient face recognition models, the submitted solutions are ranked based on a weighted score of the achieved verification accuracies on a diverse set of benchmarks, as well as the deployability given by the number of floating-point operations and model size.

Residual Feature Pyramid Network for Enhancement of Vascular Patterns

no code implementations29 Jun 2023 Ketan Kotwal, Sebastien Marcel

The accuracy of finger vein recognition systems gets degraded due to low and uneven contrast between veins and surroundings, often resulting in poor detection of vein patterns.

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.
