[Insight-users] medial curve image filter

[Sergio Vera]

Filipa

Just to clarify, ignore me if you have done it already: the code included in
the link that Xavier has provided is not included (yet) into the standard
ITK, so you have to download the source code of that article and
copy/include the required .h and .txx files into your our source tree.

Also, notice that most (if not all) ITK filters (including the filters that
you found in the insight journal, as MedialCurveImageFilter, aren't *.cpp
but *.txx
