Over time more and more complex segmentation methods
were defined like neural network based methods [9] or
perceptual segmentation methods [10]. Nevertheless a
universal segmentation method has not yet been developed.
Most methods are developed for practical applications and are
only useful for certain types of images. Since skin lesions
images used for melanoma risk evaluation are a particular class
of color images using image segmentation will require the
development of a particular segmentation method.
