BRDF estimation for faces from a sparse dataset using a neural network (2013)
Presentation / Conference Contribution

We present a novel �ve source near-infrared photometric
stereo 3D face capture device. The accuracy of the system is demonstrated by a comparison with ground truth from a commercial 3D scanner. We also use the data from the �ve captured images to mo... Read More about BRDF estimation for faces from a sparse dataset using a neural network.

Face recognition and verification using photometric stereo: The photoface database and a comprehensive evaluation (2013)
Journal Article

This paper presents a new database suitable for both 2-D and 3-D face recognition based on photometric stereo (PS): the Photoface database. The database was collected using a custom-made four-source PS device designed to enable data capture with mini...

3D face recognition using photometric stereo (2012)
Thesis

Automatic face recognition has been an active research area for the last four decades. This thesis explores innovative bio-inspired concepts aimed at improved face recognition using surface normals. New directions in salient data representation are e... Read More about 3D face recognition using photometric stereo.

Twins 3D face recognition challenge (2011)
Presentation / Conference Contribution

Existing 3D face recognition algorithms have achieved high enough performances against public datasets like FRGC v2, that it is difficult to achieve further significant increases in recognition performance. However, the 3D TEC dataset is a more chall... Read More about Twins 3D face recognition challenge.

Psychologically inspired dimensionality reduction for 2D and 3D Face Recognition (2011)
Presentation / Conference Contribution

We present a number of related novel methods for reducing the dimensionality of data for the purposes of 2D and 3D face recognition. Results from psychology show that humans are capable of very good recognition of low resolution images and caricature...

Biologically inspired 3D face recognition from surface normals (2010)
Presentation / Conference Contribution

A major consideration in state-of-the-art face recognition systems is the amount of data that is required to represent a face. Even a small (64 × 64) photograph of a face has 2 12 dimensions in which a face may sit. When large (> 1MB) photographs of...
