  We propose an automatic algorithm, named SDI, for the segmentation of skin
lesions in dermoscopic images, articulated into three main steps: selection of
the image ROI, selection of the segmentation band, and segmentation. We present
extensive experimental results achieved by the SDI algorithm on the lesion
segmentation dataset made available for the ISIC 2017 challenge on Skin Lesion
Analysis Towards Melanoma Detection, highlighting its advantages and
disadvantages.
