Abstract (EN):
In this work, image regions are segmented using the Mumford-Shah method. Thus, each
region is elastically modeled by a set of image pixels and the segmentation process is
driven by image forces until the region becomes steady. Then, a merging algorithm
based on the usual intensity of lesion-image pixels is applied to connect the lesion areas
previously segmented. The contour of the merged regions approximates the lesion
border, but needs further refinements in order to conveniently represent the desired
border, particularly in terms of irregularity that is over smoothed. To overcome this
problem, the watershed method is used considering points on the smoothed contour as
seeds. This computational approach successfully detects regions on the injured skin and
extracts their contours maintaining the original irregularity.
