Alternative to GRM for big images?

Good afternoon,
With the GRM segmentation module, 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 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 ? Thanks so much for you guidance.
