Pixel Purity Index #26

Open aloboa opened 2 years ago

aloboa commented 2 years ago

I miss a PPI algorithm in EnMapBox, I suggest including it. 2 python implementations:

pysptools https://pysptools.sourceforge.io/eea.html#pixel-purity-index-ppi
https://www.spectralpython.net/class_func_ref.html#spectral.algorithms.algorithms.ppi

Not only nice, PPI is a fundamental tool for defining endmembers and thus critical in hyperspectral geological exploration. A toolbox for hyperspectral analysis cannot miss a PPI tool.

@aloboa I renamed the milestone name to just "Future release ~- Nice to have~". All features are nice to have. If not, we should not implement them at all.
