Dynamic deflectometry: A novel approach for the on-line reconstruction of specular freeform surfaces (2012)
Journal Article
Smith, L. N., Smith, M. L., Atkinson, G. A., Wedowski, R. D., Atkinson, G., Smith, M., & Smith, L. (2012). Dynamic deflectometry: A novel approach for the on-line reconstruction of specular freeform surfaces. Optics and Lasers in Engineering, 50(12), 1765-1778. https://doi.org/10.1016/j.optlaseng.2012.07.003

The dynamic inspection and reverse engineering of specular freeform surfaces is a challenge so far largely unsolved. Products produced in high quantities in industrial environments are still inspected manually which is labour intensive, expensive, mo...

Combinatorial photometric stereo and its application in 3D modeling of melanoma (2012)
Journal Article
Smith, M. L., Zhou, Y., Smith, M., Smith, L., & Warr, R. (2012). Combinatorial photometric stereo and its application in 3D modeling of melanoma. Machine Vision and Applications, 23(5), 1029-1045. https://doi.org/10.1007/s00138-011-0356-6

This article concerns a new type of photometric stereo algorithm for which outliers such as highlights and shadows, including attached and cast shadow, are mixed with Lambertian data. The underlying motivation behind this algorithm is very simple: an... Read More about Combinatorial photometric stereo and its application in 3D modeling of melanoma.

A robust multi-scale integration method to obtain the depth from gradient maps (2012)
Journal Article
Smith, M. L., Atkinson, G. A., Leitão, H. C., Saracchini, R. F., Saracchini, R., Stolfi, J., …Smith, M. (2012). A robust multi-scale integration method to obtain the depth from gradient maps. Computer Vision and Image Understanding, 116(8), 882-895. https://doi.org/10.1016/j.cviu.2012.03.006

We describe a robust method for the recovery of the depth map (or height map) from a gradient map (or normal map) of a scene, such as would be obtained by photometric stereo or interferometry. Our method allows for uncertain or missing samples, which... Read More about A robust multi-scale integration method to obtain the depth from gradient maps.

Distribution quantification on dermoscopy images for computer-Assisted diagnosis of cutaneous melanomas (2012)
Journal Article
Liu, Z., Sun, J., Smith, L., Smith, M., & Warr, R. (2012). Distribution quantification on dermoscopy images for computer-Assisted diagnosis of cutaneous melanomas. Medical and Biological Engineering and Computing, 50(5), 503-513. https://doi.org/10.1007/s11517-012-0895-7

Computerised analysis on skin lesion images has been reported to be helpful in achieving objective and reproducible diagnosis of melanoma. In particular, asymmetry in shape, colour and structure reflects the irregular growth of melanin under the skin...

Branch cutting algorithm for unwrapping photoelastic phase map with isotropic point (2012)
Journal Article
Lao, F. Y., Liang, H. R., Huang, M. J., Zhang, Y. T., Wedowski, R., Atkinson, G., …Smith, L. (2012). Branch cutting algorithm for unwrapping photoelastic phase map with isotropic point. Optics and Lasers in Engineering, 50(5), 619-631. https://doi.org/10.1016/j.optlaseng.2011.10.013

A branch cutting algorithm is proposed to solve the wrapped isoclinic causing isochromatic discontinuity and thus to decouple the isoclinicisochromatic interaction of photoelastic phase maps. Rather than pixel by pixel, the branch-cutting isoclinic w... Read More about Branch cutting algorithm for unwrapping photoelastic phase map with isotropic point.

Unsupervised sub-segmentation for pigmented skin lesions (2012)
Journal Article
Liu, Z., Sun, J., Smith, M., Smith, L., & Warr, R. (2012). Unsupervised sub-segmentation for pigmented skin lesions. Skin Research and Technology, 18(1), 77-87. https://doi.org/10.1111/j.1600-0846.2011.00534.x

Background: Early identification of malignant melanoma with the surgical removal of thin lesions is the most effective treatment for skin cancers. A computer-aided diagnostic system assists to improve the diagnostic accuracy, where segmenting lesion... Read More about Unsupervised sub-segmentation for pigmented skin lesions.

Face recognition in 2D and 2.5D using ridgelets and photometric stereo (2012)
Journal Article
Smith, M. L., Atkinson, G. A., Kautkar, S. N., Kautkar, S., Atkinson, G., & Smith, M. (2012). Face recognition in 2D and 2.5D using ridgelets and photometric stereo. Pattern Recognition, 45(9), 3317-3327. https://doi.org/10.1016/j.patcog.2012.03.007

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.
