Comment(by wenzeslaus):

 Does the following helps?

 Pietro Zambelli in [http://lists.osgeo.org/pipermail/grass-
 dev/2014-January/066819.html Object-based image classification in GRASS]
 at grass-dev ([http://osgeo-org.1560.x6.nabble.com/Object-based-image-
 classification-in-GRASS-td5086693.html nabble]):

 v.stats r58637 => Extract statistics from a vector map
        (statistics about shape and about raster maps).
        v.stats internally use (in grass-addons):
         - v.area.stats r58636 => extract some statistics about
           the shape (in grass-addons);
         - v.to.rast => re-convert the vector to a raster map using the
           vector categories to be sure that there is a correspondence
           between vector and raster categories (zones).
         - r.univar2 r58439 => extract some general statistics from
           raster using the zones (consume much less memory than
           r.univar, and compute more general statistics like:
           skewness, kurtosis, and mode (in grass-addons);
