public class SoAutoIntensityClassificationProcessing
extends SoImageVizEngine

SoAutoIntensityClassificationProcessing classifies all pixels/voxels of an image using the k-means method. Given a set of observations (x1, x2, ..., xn), where each observation is a d-dimensional real vector, k-means clustering aims to partition the n observations into k (= n) sets S = {S1, S2, ..., Sk} so as to minimize the within-cluster sum of squares (WCSS) (sum of distance functions of each point in the cluster to the K center).
