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...

Obtaining malignant melanoma indicators through statistical analysis of 3D skin surface disruptions (2009)
Journal Article

Background/purpose: It has been observed that disruptions in skin patterns are larger for malignant melanoma (MM) than benign lesions. In order to extend the classification results achieved for 2D skin patterns, this work intends to investigate the f...

Concealed object perception and recognition using a photometric stereo strategy (2009)
Presentation / Conference Contribution

Following a review of current hidden objects detection techniques in a range of security applications, a strategy based on an innovative, low-cost photometric stereo technique is proposed to reveal concealed objects. By taking advantage of informatio... Read More about Concealed object perception and recognition using a photometric stereo strategy.

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

Reflectance of human skin using colour photometric stereo: With particular application to pigmented lesion analysis (2008)
Journal Article

Background/purpose: The optical appearance of human skin is highly dependent on the interaction between the illumination (type and position), observer position and the skin surface structure. Different currently available photographic techniques reco... Read More about Reflectance of human skin using colour photometric stereo: With particular application to pigmented lesion analysis.

Improving the human readability of features constructed by genetic programming (2007)
Presentation / Conference Contribution

Object surface recovery using a multi-light photometric stereo technique for non-Lambertian surfaces subject to shadows and specularities (2007)
Journal Article

This paper presents a new multi-light source photometric stereo system for reconstructing images of various characteristics of non-Lambertian rough surfaces with widely varying texture and specularity. Compared to the traditional three-light photomet...

3D convolutional neural network for home monitoring using low resolution thermal-sensor array
Presentation / Conference Contribution

The recognition of daily actions, such as walking, sitting or standing, in the home is informative for assisted living, smart homes and general health care. A variety of actions in complex scenes can be recognised using visual information. However ca...
