Hi, The limit in terms of memory depends on the amount of available ram in your machine at the time of processing. Morphological profiles are very greedy in terms of memory and CPU.
You may try to use tiles of smaller size (vector mode instead of raster: "-mode.vector.tilesize"). About your problem number 2: I guess your computer turns off in order to avoid dying by getting too hot, but this is not OTB's fault ;) Jordi pierre-alban hugueny <[email protected]> wrote: > > Hello, > > I contact you today for a different problem but always on the segmentation > tools from OTB . > > First problem: > > I use the picture IMG_0613 (which is not attached cause of the restriction: > 2000x2000 pixels max.).
