Hi, Here is the reference paper for VCA:
http://www.lx.it.pt/~bioucas/files/ieeegrsVca04.pdf <http://www.lx.it.pt/%7Ebioucas/files/ieeegrsVca04.pdf> The algorithm extract pixels inside the input dataset as endmembers and exploits the fact that endmem- bers occupy the vertices of a simplex. Please report a bug if you still don't understand the output of the application with your data.
