[Insight-users] Compile fails for BinaryMorphologicalOpeningImageFilter

[Luis Ibanez]

Hi Denis,

Thanks for pointing out this bug.

A fix has now been pushed to the
Gerrit code review system:

http://review.source.kitware.com/#change,272

It should move swiftly into the git master branch of ITK...


     Thanks


          Luis
