WebMean shift is an application-independent tool suitable for real data analysis. Does not assume any predefined shape on data clusters. It is capable of handling arbitrary feature spaces. The procedure relies on choice of a single parameter: bandwidth. The bandwidth/window size 'h' has a physical meaning, unlike k -means.
