i would like to get this kind of results this time for a bigger area / big image. But with GRM, i get error memory message because this module does not support large image. Could you advise me/direct me towards an orfeo segmentation or another grass, qgis
tool / associated parameters & settings that would support large input images and that would allow me to obtain this type of segmentation results (hight size of segments,segments that have a high heterogeneity acceptance threshold ).Maybe module as "LSMSSegmentation"
or " LargeScaleMeanShift" would be appropriate/relevant ?<o:p></o:p></span></p>
