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...

An automated mean-shift based segmentation for pigmented skin lesions (2010)
Presentation / Conference Contribution
This paper presents an unsupervised segmentation scheme to isolate pigmented skin lesion from surrounding normal skin. An adaptive mean-shift algorithm combined with maximal
similarity based region merging is applied with a colour-spatial feature sp... Read More about An automated mean-shift based segmentation for pigmented skin lesions.
A computer assisted diagnosis system for malignant melanoma using 3D skin surface texture features and artificial neural network (2010)
Journal Article
It has been observed that disruptions in skin patterns are larger for malignant melanoma than for benign lesions. In contrast to existing work on 2D skin line patterns, this work proposes a computer assisted diagnosis system for malignant melanoma ba...

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.
A new method describing border irregularity of pigmented lesions (2010)
Journal Article
Background/purpose: Automatic quantitative characterization of border irregularity generating useful descriptors is a highly important task for computer-aided diagnosis of melanoma. This paper proposes a novel approach to describe the border irregula... Read More about A new method describing border irregularity of pigmented lesions.
Using 3D differential forms to characterize a pigmented lesion in vivo (2010)
Journal Article
Background/purpose: After the formulation of ABCD rules, many new feature extraction methods are emerging to describe the asymmetry, border irregularity, color variation and diameter of malignant melanoma. In this paper, a new research direction orth... Read More about Using 3D differential forms to characterize a pigmented lesion in vivo.
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.
