This program runs the segmentation of a 2D image by applying a localized k-means approach that helps to overcome intensity inhomogeneities in the image. The approach evaluates a global k-means clustering, and then separates the image into overlapping regions where more k-means iterations are run only including the locally present classes, i.e. the classes that relatively contain more pixels than a given threshold.
