[GRASS-dev] wxGUI: supervised classification tool

[Pierre Roudier]

Hi Markus et al.,

Just to throw my two cents, it would be great if we could generalise
this UI to any classification workflow, including unsupervised. I
could also see this UI as a nice way to integrate r.fuzzy.* maybe?

Also, the excellent work on Markus M and Eric Momsen on i.segment
could also be integrated alongside the older i.smap.

Neat stuff,

Pierre
