@phcerdan Thanks for your reply! I just pushed a new version of NeighborhoodRange onto Gerrit, with added support for arbitrarily shaped neighborhoods: Patch Set 8, [http://review.source.kitware.com/#/c/23326/8](http://review.source.kitware.com/#/c/23326/8)

Is it possible for you to try out the patch? If so, can you please do the same performance test again, from [Removal of `virtual` keywords from ConstNeighborhoodIterator](https://discourse.itk.org/t/removal-of-virtual-keywords-from-constneighborhooditerator/814/5) ?
