[ITK-users] 3-D support for BinaryPruningImageFilter

[Anchit Dhar]

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.
