According to Haralick's publications, the texture measurements can be used for image classification. Could you update the manual if you can suggest applications for these texture measurments? Thanks! I just committed what I consider some improvements, including a very simple, but thus hopefully pedagogical, example. I allowed myself to rearrange some of the existing text, including some of your recent additions. Please have a look and if you think this is ok, we can backport to the other branches. -- Ticket URL: <https://trac.osgeo.org/grass/ticket/3210#comment:26> GRASS GIS <https://grass.osgeo.org> _______________________________________________ grass-dev mailing list grass-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-dev
