Using nasal curves matching for expression robust 3D nose recognition (2013)
Presentation / Conference
Emambakhsh, M., Evans, A., & Smith, M. (2013, September). Using nasal curves matching for expression robust 3D nose recognition. Paper presented at IEEE Conference on Biometrics: Theory, Applications and Systems (BTAS2013)

The development of 3D face recognition algorithms that are robust to variations in expression has been a challenge for researchers over the past decade. One approach to this problem is to utilize the most stable parts on the face surface. The nasa... Read More about Using nasal curves matching for expression robust 3D nose recognition.

BRDF estimation for faces from a sparse dataset using a neural network (2013)
Presentation / Conference
Hansen, M. F., Atkinson, G., & Smith, M. (2013, August). BRDF estimation for faces from a sparse dataset using a neural network. Paper presented at Computer Analysis of Images and Patterns, CAIP 2013

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.

Face recognition and verification using photometric stereo: The photoface database and a comprehensive evaluation (2013)
Journal Article
Smith, L. N., Smith, M. L., Hansen, M. F., Atkinson, G. A., Zafeiriou, S., Atkinson, G., …Smith, L. (2013). Face recognition and verification using photometric stereo: The photoface database and a comprehensive evaluation. IEEE Transactions on Information Forensics and Security, 8(1), 121-135. https://doi.org/10.1109/TIFS.2012.2224109

This paper presents a new database suitable for both 2-D and 3-D face recognition based on photometric stereo (PS): the Photoface database. The database was collected using a custom-made four-source PS device designed to enable data capture with mini...

In order to achieve an early detection of skin cancers, various state-of-the-art imaging modalities have been investigated from optical, impedance, biomechanical and physiological perspectives to find out the potential biomarkers. However multilayere... Read More about Recovering skin reflectance and geometry for diagnosis of melanoma.

Incorporating clinical metadata with digital image features for automated identification of cutaneous melanoma (2013)
Journal Article
Liu, Z., Sun, J., Smith, M., & Smith, L. (2013). Incorporating clinical metadata with digital image features for automated identification of cutaneous melanoma. British Journal of Dermatology,

Abstract Background Computer-assisted diagnosis (CAD) of malignant melanoma (MM) has been advocated to help clinicians in achieving a more objective and reliable assessment. However, conventional CAD systems only examine the features extracted from...

Existing face imaging systems are not suitable to meet the face representation and recognition demands for emerging applications in areas such as interactive gaming, enhanced learning environments and directed advertising. This is mainly due to the p... Read More about Real-time recovery of moving 3D faces for emerging applications.

Robust 3D face capture using example-based photometric stereo (2013)
Journal Article
Smith, M. L., Atkinson, G. A., Leitão, H. C., Saracchini, R. F., Saracchini, R., Stolfi, J., …Smith, M. (2013). Robust 3D face capture using example-based photometric stereo. Computers in Industry, 64(9), 1399-1410. https://doi.org/10.1016/j.compind.2013.04.003

We show that using example-based photometric stereo, it is possible to achieve realistic reconstructions of the human face. The method can handle non-Lambertian reflectance and attached shadows after a simple calibration step. We use spherical harmon...

Multidimensional imaging for skin tissue surface characterization (2013)
Journal Article
Sun, J., & Smith, M. (2013). Multidimensional imaging for skin tissue surface characterization. Computers in Industry, 64(9), 1383-1389. https://doi.org/10.1016/j.compind.2013.06.004

Human skin, the outer and largest organ covering our body, can be described in terms of both its 3D spatial topography and its 2D spectral reflectance. Such a characterization normally requires the application of separate procedures using different k... Read More about Multidimensional imaging for skin tissue surface characterization.
