Unmixing based on VCA

VCA algorithm to obtain the k endmembers from the signatures.

unmixing_vca(signatures, k)

Arguments

signatures	A spectral object built using the load_signature_files function.
k	The number of endmembers to find.

Value

An extended spectral object which includes the indices of the endmember signatures.
