Hi,
Is it possible that no python wrapper exists for the LabelOverlapMeasuresImageFilter class?
If necessary, I can take a shot at adding the wrapper if someone would point me in the right direction.
Tested on itk 4.13.0 (pip installed and own build).
Thanks,
Christophe

Hello,
Yes, ITK Python does appear not to have a wrapping file:
> **[InsightSoftwareConsortium/ITK](https://github.com/InsightSoftwareConsortium/ITK/tree/master/Modules/Filtering/ImageStatistics/wrapping)**
>
> Insight Toolkit (ITK) -- Official Repository. Contribute to InsightSoftwareConsortium/ITK development by creating an account on GitHub.
The [ITK Software Guide](https://itk.org/ItkSoftwareGuide.pdf) contains a section (9.5 Wrapping) devoted to explain how wrapping can be done in ITK. It should not be a hard filter to wrap.
If you need immediate access to this filter, I will also shamelessly plug that SimpleITK [already has it](https://itk.org/SimpleITKDoxygen/html/classitk_1_1simple_1_1LabelOverlapMeasuresImageFilter.html). Additionally, there is a very nice SimpleITK notebook demonstrating its usage:

Thank you Bradley for the quick reply. I’ll have a look at both resources!
