Hello, I'm taking the liberty to post a message. I work with windows 11, Qgis 3.34.13. I work with OrfeoToolbox 9 via Qgis interface (GenericRegionMerging segmentation module). Please find below the characteristics of my Windows station:
Name of the operating system Microsoft Windows 11 Professional > Type PC based on x64 > Processor 13th Gen Intel(R) Core(TM) i7-13700H, 2400 MHz, 14 core(s), 20 > logical processor(s) > Installed physical memory (RAM) 32.0 GB > Total physical memory 31.7 GB > Available physical memory 17.8 GB > Total virtual memory 39.4 GB > Available virtual memory 23.0 GB > Space for the swap file 7.75 GB I manage to generate segmentations without error messages on small areas. But as soon as my input image is larger, I am faced with problems probably memory limitations. I share the error messages. Could you share some recommendations? Should I change the memory allocation currently allocated to Orfeotoolbox? To Qgis? Or change the strategy in terms of processor solicitation? 2025-02-24 10:39:57 (INFO) GenericRegionMerging: Default RAM limit for OTB is 256 MB 2025-02-24 10:39:57 (INFO) GenericRegionMerging: GDAL maximum cache size is 1621 MB 2025-02-24 10:39:57 (INFO) GenericRegionMerging: OTB will use at most 20 threads 2025-02-24 10:39:57 (INFO): Loading metadata from official product 2025-02-24 10:45:37 (FATAL) GenericRegionMerging: Caught std::exception during application execution: bad allocation Execution completed in 361.86 secondes (6 minutes 2 secondes) Résultats: XXXXXXXXXXXXX/Process/AE_GRM_100_0.9_0.5.tif'} Many thanks.
