Texture Information in Melanocytic Skin Lesion Analysis Based on Standard Camera Images

The classification of melanocytic skin lesions is a very difficult task, and usually computer-aided diagnosis systems or screening systems focus on reproducing medical criteria as the ABCD rule. However, the texture information can also contribute significantly for the lesion classification, since malignant cases tends to present texture patterns different from benign cases. In this chapter, we detail five representative sets of features that have been proposed in the literature for the representation of melanocytic lesions texture information, and then we analyze how these features distinguish between malignant and benign classes using two well known classifiers.
