#3427 closed enhancement (fixed)

Ask for improvement of i.segment.stats : Allow parallel work for different rasters

I would like to ask for an improvement of i.segment.stats add-on. For the moment, the processing workflow is serial (objects statistics computed for the first band, e.g. blue, then on red, then on green, etc..). It could be great if the process could be parallelized on X different cores. I'm often computing objects statistics on +10 different rasters. This improvement would allow for saving a lot of processing time.


PS: Thank you for making GRASS more and more efficient for Object-Based image analysis.

Please test new version.

Tested on Linux Mint 18.1 (MATE 64bits) and GRASS 7.3.svn (r71315). Works perfectly. Thanks for the improvement.
