Bi-Modal Person Recognition on a Mobile Phone: using mobile phone data

Sébastien Marcel, Norman Hoon Thian Poh, Timothy Cootes

This paper presents a novel fully automatic bi-modal, face and speaker, recognition system which runs in real-time on a mobile phone. The implemented system runs in real-time on a Nokia N900 and demonstrates the feasibility of performing both automatic fac ...

Bi-Modal Person Recognition on a Mobile Phone: using mobile phone data

Sébastien Marcel, Norman Hoon Thian Poh, Timothy Cootes

Idiap2012

This paper evaluates the performance of face and speaker verification techniques in the context of a mobile environment. The mobile environment was chosen as it provides a realistic and challenging test-bed for biometric person verification techniques to o ...

The Multiscenario Multienvironment BioSecure Multimodal Database (BMDB)

Norman Hoon Thian Poh, Jonas Richiardi, Andrzej Drygajlo, Jean Hennebert

A new multimodal biometric database designed and acquired within the framework of the European BioSecure Network of Excellence is presented. It is comprised of more than 600 individuals acquired simultaneously in three scenarios: 1) over the Internet, 2) i ...

Multi-system biometric authentication

Norman Hoon Thian Poh

Verifying a person's identity claim by combining multiple biometric systems (fusion) is a promising solution to identity theft and automatic access control. This thesis contributes to the state-of-the-art of multimodal biometric fusion by improving the und ...

EPFL2007

Biometric authentication performance is often depicted by a DET curve. We show that this curve is dependent on the choice of samples available, the demographic composition and the number of users specific to a database. We propose a two-step bootstrap proc ...

Multi-system Biometric Authentication: Optimal Fusion and User-Specific Information

Norman Hoon Thian Poh

École Polytechnique Fédérale de Lausanne2006

Chimeric users have recently been proposed in the field of biometric person authentication as a way to overcome the problem of lack of real multimodal biometric databases as well as an important privacy issue -- the fact that too many biometric modalities ...

Revisiting Doddington's Zoo: A Systematic Method to Assess User-dependent Variabilities

Samy Bengio, Norman Hoon Thian Poh

A systematic analysis of user-dependent performance variability in the context of automatic speaker verification was first studied by Doddington \etal (1998). Different categories of users were distinguished and were called by animal names such as sheep, g ...
