Hello,<br>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:<br><br><br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Name of the operating system Microsoft Windows 11 Professional<br>Type PC based on x64<br>Processor 13th Gen Intel(R) Core(TM) i7-13700H, 2400 MHz, 14 core(s), 20 logical processor(s)<br>Installed physical memory (RAM) 32.0 GB<br>Total physical memory 31.7 GB<br>Available physical memory 17.8 GB<br>Total virtual memory 39.4 GB<br>Available virtual memory 23.0 GB<br>Space for the swap file 7.75 GB</blockquote><br>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.<br>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? <br><br><blockquote><br>2025-02-24 10:39:57 (INFO) GenericRegionMerging: Default RAM limit for OTB is 256 MB<br>2025-02-24 10:39:57 (INFO) GenericRegionMerging: GDAL maximum cache size is 1621 MB<br>2025-02-24 10:39:57 (INFO) GenericRegionMerging: OTB will use at most 20 threads<br>2025-02-24 10:39:57 (INFO): Loading metadata from official product<br>2025-02-24 10:45:37 (FATAL) GenericRegionMerging: Caught std::exception during application execution: bad allocation<br>Execution completed in 361.86 secondes (6 minutes 2 secondes)<br>Résultats:<br>XXXXXXXXXXXXX/Process/AE_GRM_100_0.9_0.5.tif'}</blockquote>
Many thanks.
