Buenos días
Tengo unos puntos con los que deseo crea una ruta optima entre ellos, hay alguna herramienta para crear la ruta optima usando todos los puntos.

Asunto: [Qgis-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<https://protect.checkpoint.com/v2/r02/___https:/www.orfeo-toolbox.org/CookBook-8.1/Applications/app_GenericRegionMerging.html___.YzJlOmNvcnJlb3NkZWNvc3RhcmljYXNhOmM6bzowZWY4ZTlhZjJhN2E1MGIwMjIwYmE5ZWRmZjIxYjgwNzo3OjhlZjU6MzA0NDczOGNiZTEwMmUwYWE5ODk4ZGJkZWQ0ZDg4OGE2MWIxZWYyNmRmZmYwYzZmMzIwNzBmMDAzYTExNDUyOTpoOlQ6Tg>
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 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 ?
