Face recognition in 2D and 2.5D using ridgelets and photometric stereo (2012)
Journal Article

A new technique for face recognition - Ridgefaces - is presented. The method combines the well-known Fisherface method with the ridgelet transform and high-speed Photometric Stereo (PS). The paper first derives ridgelet projections for 2D/2.5D face i... Read More about Face recognition in 2D and 2.5D using ridgelets and photometric stereo.

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...

An efficient and practical 3D face scanner using near infrared and visible photometric stereo (2010)
Presentation / Conference Contribution

This paper is concerned with the acquisition of model data for automatic 3D face recognition applications. As 3D methods become progressively more popular in face recognition research, the need for fast and accurate data capture has become crucial. T...

Presentation / Conference Contribution

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...

Multi-scale depth from slope with weights (2010)
Presentation / Conference Contribution

We describe a robust method to recover the depth coordinate from a normal or slope map of a scene, obtained e.g. through photometric stereo or interferometry. The key feature of our method is the fast solution of the Poisson-like integration equation... Read More about Multi-scale depth from slope with weights.

3D face reconstructions from photometric stereo using near infrared and visible light (2010)
Journal Article

This paper seeks to advance the state-of-the-art in 3D face capture and processing via novel Photometric Stereo (PS) hardware and algorithms. The first contribution is a new high-speed 3D data capture system, which is capable of acquiring four raw im...

Correlating plagiocephaly skull deformations with facial asymmetry using projected pattern 3D imaging (2010)
Book Chapter

In this paper, we present a statistical study into skull deformations caused by positional plagiocephaly. We also consider the hardware used for the assessment of both severity and treatment. State-of-the-art external imaging hardware is employed to... Read More about Correlating plagiocephaly skull deformations with facial asymmetry using projected pattern 3D imaging.

Facial geometry estimation using photometric stereo and profile views (2009)
Presentation / Conference Contribution

This paper presents a novel method for estimating the three-dimensional shape of faces, facilitating the possibility of enhanced face recognition. The method involves a combined use of photometric stereo and profile view information. It can be divide... Read More about Facial geometry estimation using photometric stereo and profile views.

Facial reconstruction and alignment using photometric stereo and surface fitting (2009)
Presentation / Conference Contribution

This paper presents a novel 3D face shape capture device suitable for practical face recognition applications. A new surface fitting based face alignment algorithm is then presented to normalise the pose in preparation for recognition. The 3D data ca...
