[GRASSLIST:1764] Subpixel classification

Hello Grass Community,

I am working on a project where I would like to determine tree cover
density from Landsat 7 data. After looking around on the web a bit, I
found that the IMAGINE Subpixel Classifier could determine % tree
cover/pixel. Is there any way to do something like this in GRASS?

Thanks in advance!
