<p class="MsoNormal">i obtain interesting results for small images/area , for instance for one input ortho image (3 bands) . Please see result below :

<img border="0" width="578" height="343" style="width:6.0166in;height:3.575in" id="Imagen_x0020_1" src="cid:image001.png@01DB918D.0058AFB0"><br>
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 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 ? <br>
