Obtaining malignant melanoma indicators through statistical analysis of 3D skin surface disruptions (2009)
Journal Article
Ding, Y., Smith, L., Smith, M., Sun, J., & Warr, R. (2009). Obtaining malignant melanoma indicators through statistical analysis of 3D skin surface disruptions. Skin Research and Technology, 15(3), 262-270. https://doi.org/10.1111/j.1600-0846.2009.00352.x

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...
