of Skin-Cancer Images - Implementation of an algorithm for
segmenting images of skin cancer and other pigmented lesions (see Image
and Vision Computing, January 1999, pp. 65-74).
An automatic method
for segmention of images of skin cancer and other pigmented lesions is implemented.
This method first reduces a color image into an intensity image and approximately
segments the image by intensity thresholding. Then, it refines the segmentation
using image edges. Double thresholding is used to focus on an image area
where a lesion boundary potentially exists. Image edges are then used to
localize the boundary in that area. A closed elastic curve is fitted to
the initial boundary and is locally shrunk or expanded to approximate edges
in its neighborhood in the area of focus. Segmentation results from twenty
randomly selected images show an average error that is about the same as
that obtained by four experts manually segmenting the images. (by L.
