[ITK-users] 3-D support for BinaryPruningImageFilter

[Dženan Zukić]

Hi Anchit,

I took a look at the source
<https://github.com/InsightSoftwareConsortium/ITK/blob/master/Modules/Filtering/BinaryMathematicalMorphology/include/itkBinaryPruningImageFilter.hxx>
code, and it does seem to be 2D-only.

Hello,
I have written a module to prune branches of a 3-D Skeleton using ITK’s BinaryPruningImageFilter.
The filter is returning unexpected pruned results for a 3-D skeleton input.
The doxygen page
<https://itk.org/Doxygen/html/classitk_1_1BinaryPruningImageFilter.html>
for the filter states that –
*“The algorithm is the N-dimensional version of that given for two
dimensions in: Rafael C. Gonzales and Richard E. Woods. Digital Image
<https://itk.org/Doxygen/html/classitk_1_1Image.html> Processing. Addison
Wesley, 491-494, (1993).”*
But, from the source code of BinaryPruningImageFilter it appears that
pruning is being performed considering 2-D neighbors only and hence does
not support 3-D. Can someone please confirm this?
Thanks.
