Hi, at the moment I guess the only way to speed up it is exactly what suggested by Moritz:

I've used this module to segment an image (RGB) of 24 x 48 kpixels on my laptop in less than 12 hours (if I remeber correctly). Still I think we can reach greater improvement working at C level but I didn't have time to work on it I have just some ideas, no code. All the best Pietro _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
