The European Biometrics Research Award goes to an Idiaper

In the face recognition research field, new challenges are going harder as the field limits are expanding. Tiago de Freitas Pereira award from the European Association for Biometrics is a significant recognition for his work during his thesis.

Face recognition systems have been proposed over the last three decades. Ranging from visual light images to infrared ones, various technologies are available. Being able to mix various recognition methods is a key element to provide a more accurate solution. In his thesis Tiago de Freitas Pereira from Idiap’s Biometrics security & privacy group looked how to combine these various technologies to apply them in so called heterogeneous face recognition situations. The key difficulty in the comparison of faces in such conditions is that images from the same subject may differ in appearance due to changes in image domain. Tiago’s work proposes a method to address this difficulty.

Using mathematical tools

In his research, Tiago analysed if the features used in visual light face recognition situation can also be applied in other light situations. Then using various mathematical tools, he showed that data from these facial recognition systems can be compared and used together for facial recognition. Then, large-scale experiments were conducted on several heterogeneous face recognition databases, covering various image domains showing competitive performances.

Moreover, the implementation of all the proposed techniques is integrated into a collaborative open source software library called Bob. The aim is to enforces fair evaluations and encourages reproducible research.
