1. A method for the analysis of image data represented by multiple pixels, the method characterized by: determining a texture value for at least a portion of each of the multiple pixels; initially assigning each of the at least a portion of multiple pixels to one of two or more groups based upon respective determined texture values; calculating an initial statistical distance between at least one pixel and each initial centroid of the two or more groups; comparing each of the calculated initial statistical distances of the at least one pixel with each other; and depending upon the comparison result, reassigning the at least one pixel into a different one of the two or more groups.
