Segmentationof Skin-Cancer Images Implementation of an algorithm forsegmenting images of skin cancer and other pigmented lesions (seeImage and Vision Computing, January 1999, pp. 65-74).
Anautomatic method for segmention of images of skin cancer and otherpigmented lesions is implemented. This method first reduces a colorimage into an intensity image and approximately segments the image byintensity thresholding. Then, it refines the segmentation using imageedges. Double thresholding is used to focus on an image area where alesion boundary potentially exists. Image edges are then used tolocalize the boundary in that area. A closed elastic curve is fittedto the initial boundary and is locally shrunk or expanded toapproximate edges in its neighborhood in the area offocus. Segmentation results from twenty randomly selected images showan average error that is about the same as that obtained by fourexperts manually segmenting the images. (by L. Xu, M. Jackowski, A.
