Two-source surface reconstruction using polarisation (2017)
Presentation / Conference Contribution

© Springer International Publishing AG 2017. Polarisation vision aims to capture and interpret the polarisation state of incoming light as part of a computer vision system. In this paper, polarisation information is fused with two-source photometric... Read More about Two-source surface reconstruction using polarisation.

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.

Multi-scale integration of slope data on an irregular mesh (2011)

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...

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...

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.

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...

High-precision polarization measurements and analysis for machine vision applications
Presentation / Conference Contribution

Polarization is a source of information that is steadily attracting attention in the field of computer vision due to its ability to tap into information not readily available in standard colour or greyscale cameras. Unfortunately, most existing data... Read More about High-precision polarization measurements and analysis for machine vision applications.
