Hausdorff Distance

Hello!
I compute Dice and Hausdorff Distance, you can see the result. So, I know that Dice similarity ranged from 0 to 1. How Hausdorff distance was ranged? Consequently, how to interpret this result. Any explanation will be helpful. Thanks!mmexport1568627962647

Hausdorff distance is millimeters.

Here’s the wikipedia page for the Hausdorff distance that explains the concept with a helpful figure

Here is the doxygen page from the Plastimatch Hausdorff algorithm with equations (this is what the module uses, need to scroll down a bit)
http://plastimatch.org/doxygen/classHausdorff__distance.html

By the way this last link is referenced from the module documentation
https://www.slicer.org/wiki/Documentation/Nightly/Modules/SegmentComparison

It is generally a good idea to look at the documentation, as many times you will find useful information there.

Thank!Emoji

on a related note…does anyone have any information on whether the plastimatch Hausdorff or DICE calculations have been validated against any other viable option?

Yes, we validated it against analytic solids prior to using it to score the MICCAI 2015 H&N Grand Challenge. That means comparing translated and resized cubes, spheres, and cylinders, and comparing against the analytic solution.

Thanks Greg - are there any publications or links to details available anywhere?
