[GRASS-user] Alternative to orfeoToolBox GRM segmentation module for big images?

Good afternoon ,

With the orfeo GRM segmentation module https://www.orfeo-toolbox.org/CookBook-8.1/Applications/app_GenericRegionMerging.html

i obtain interesting results for small images/area , for instance for one input ortho image (3 bands) . Please see result below :

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 ?

Thnaks so much.
