Hi there! I’m trying to use Segmentation in OTB with different settings to get optimal segments for a classification. so I’ve already have two .shp processed by “Segmentation”. However now it isn’t working anymore. I think it’s because of the memory capacity?
I’m using QGIS 3.22.9, Python 3.9.5, GDAL 3.51 and OTB 8.0.1. Could anybody check the protocol and please help me?
