Hi there,  
I want to use fuzzy connectedness algorithm in my project and I didn’t find it in the latest version.  
So how can I use it?

Thanks in advance.  
Best Regards,  
Nayra

As answered in the [other thread](https://discourse.itk.org/t/itksimplefuzzyconnectednessscalarimagefilter-h/1634), you need to use an old version of ITK because it has been removed due to being patented.
