Title: Segmentation of skin lesions by watershed using Mumford-Shah in the seeding process
Issue Date: 2010
Abstract: In this work, image regions are segmented using the Mumford-Shah method. Thus, eachregion is elastically modeled by a set of image pixels and the segmentation process isdriven by image forces until the region becomes steady. Then, a merging algorithmbased on the usual intensity of lesion-image pixels is applied to connect the lesion areaspreviously segmented. The contour of the merged regions approximates the lesionborder, but needs further refinements in order to conveniently represent the desiredborder, particularly in terms of irregularity that is over smoothed. To overcome thisproblem, the watershed method is used considering points on the smoothed contour asseeds. This computational approach successfully detects regions on the injured skin andextracts their contours maintaining the original irregularity.
