Fig. 5 Examples dot segmentation and lesion feature extraction of malignant melanoma (rows 1 and 2) and benign skin lesions (rows 3–5). In the left column, the segmented dots are superimposed on the original dermoscopy images. In the right column, the centers of mass of the segmented dots are shown on the original image, as well, as the with the center of mass of the segmented dark dots superimposed, along with the primary symmetry axis and the manually delineated boundary of the skin lesion.
