Hello all,
Grass classifier (i.maxlik) is well tested I think.
But grass laks a sub-pixel classifier.
But adding sub-pixel classification support to existing
Maximum Likelihood classifier seems to be easy(at least
theoretically).
Can we add this facility to i.maxlik

I have written a spectral unmixing tool for GRASS years
ago and still have to finish the update for 'gmath' lib.
On the list for this summer...

fusion and classification. International Journal of

Coming (hopefully) soon,

Good news... I hope it will be good for me(at least).
I checked i.maxlink's source code. I think converting
it into sub-pixel classifier is quite simple.
We are calculating probability vector(Or whatever it may be called),
this can direvtily give class proportions.
Should we try for this?
