It is non immediatelly clear to me how the second step (clustering) is working and I can't find help from the manual. 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?
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). Each group of cells becomes an object in the final output.
