Dear all,
I just committed a new addon (i.pysptools.unmix) which is a wrapper around the endmember extraction and spectral unmixing functionality in the pysptools python library 1.
Feedback will be gladly received!
Cheers

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

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
