Hoover metrics: some advices?

Dear all,
I am struggling to use the hoover metrics application: it takes ages on my small 2000x2000 image, I can’t have a result. After running on 6 cpus the entire week end: still running monday, and I stopped it.
Does anyone have some advice to compute these metrics? I just want to compare 2 segmentations (UInt16 images of labels).
Many thanks,

Hi Remi,

I think we used it to compare a segmentation with reference data, in which there are only a few components. The hoover metrics require to build some sort of confusion matrix between tested and reference segmentation, so if you have N segments in first and M in latter, cost is O(NxM), which may be a lot if both input are image segmentation.
