I am not understanding how this process is performed in the i.segment module, as well as if I can set it somehow. Do someone can help me with some explanation or reference about the clustering process in i.segment?<br><br></div>The clustering is the same like in r.clump: it identifies connected components by grouping neighboring cells together that are similar to each other with regard to hr (spectral bandwidth).
