Hi Moritz,
We are about to compare results from the two addons...
Unfortunately, I missed some details, so the manual page is not online yet
(issues should be fixed now).
The main additions, compared to i.spec.unmix are
- three alternative endmember detection algorithms
- (at least) two additional algorithms for spectral unmixing (Unconstrained
least squares and fully constrained least squares (with the latter, pixels
values in the resulting maps sum up to 1).
I should probably also mention, that i.pysptools.unmix allows to write out
detected end members in a format that i.spec.unmix understands. So the modules
can be complementary...
Cheers,
Stefan

Great, thanks a lot ! How does it compare to i.spec.unmix ? I assume it adds
more algorithms ?
