Title: Computational methods for the image segmentation of pigmented skin lesions: a review
Issue Date: 2016
Abstract: Background and objectives: Because skin cancer affects millions of people worldwide, computationalmethods for the segmentation of pigmented skin lesions in images have beendeveloped in order to assist dermatologists in their diagnosis. This paper aims to present areview of the current methods, and outline a comparative analysis with regards to severalof the fundamental steps of image processing, such as image acquisition, pre-processingand segmentation.Methods: Techniques that have been proposed to achieve these tasks were identified andreviewed. As to the image segmentation task, the techniques were classified according totheir principle.Results: The techniques employed in each step are explained, and their strengths and weaknessesare identified. In addition, several of the reviewed techniques are applied to macroscopicand dermoscopy images in order to exemplify their results.Conclusions: The image segmentation of skin lesions has been addressed successfully in manystudies; however, there is a demand for new methodologies in order to improve the efficiency.
