An ICA-based method for the segmentation of pigmented skin lesions in macroscopic images

Conf Proc IEEE Eng Med Biol Soc. 2011;2011:5993-6. doi: 10.1109/IEMBS.2011.6091481.


Segmentation is an important step in computer-aided diagnostic systems for pigmented skin lesions, since that a good definition of the lesion area and its boundary at the image is very important to distinguish benign from malignant cases. In this paper a new skin lesion segmentation method is proposed. This method uses Independent Component Analysis to locate skin lesions in the image, and this location information is further refined by a Level-set segmentation method. Our method was evaluated in 141 images and achieved an average segmentation error of 16.55%, lower than the results for comparable state-of-the-art methods proposed in literature.
