    Abstract

    This paper presents an algorithm for classification of nonmelanoma
    skin lesions based on a novel hierarchical KNearest Neighbors (K-NN) classifier. The K-NN classifier is simple, quick and effective. The hierarchical structure
    decomposes the classification task into a set of simpler problems, one at each node of the classification. Feature selection is embedded in the hierarchical framework that chooses the most relevant feature subsets at each node of the hierarchy. Colour and texture features are extracted from skin lesions. The accuracy of the proposed hierarchical scheme is higher than 93% in discriminating cancer and pre-malignant lesions from benign lesions, and it reaches an overall classification accuracy of 74% over five common classes of skin lesions, including two non-melanoma cancer types. This is the most
    extensive published result on non-melanoma skin cancer classification from colour images acquired by a standard camera (non-dermoscopy).
