[Insight-users] bug in Morphology with parabolic structuring elements?

[Oleksandr Dzyubak]

Dear ITK users,

Recently I tried classes "Morphology with parabolic structuring 
elements" by Richard Beare.
Since it is not available in the ITK lib yet,
I downloaded the submission version from the link below.

http://www.insight-journal.org/browse/publication/228

BTW, on the submission page there is a recommendation which basically 
does not work.

If I click on the provided link,
it gives (me at least) the error message "You cannot access this item!"

In submission everything compiles well and provided examples work.
I am, in particular, interested in "Open-Close" morphological operations.
Richard provided an example testOpen.cxx which works
and produces reasonable results.
Thus, I took it as basis to build testClose.cxx.

To make my life easier, I included
#include "itkParabolicCloseImageFilter.h"

and substituted
 typedef itk::ParabolicOpenImageFilter< IType,IType > FilterType;
with
  typedef itk::ParabolicCloseImageFilter< IType,IType > FilterType;

After those manipulations, I was able to succesfully compile my code 
testClose.cxx.
However, as opposed to testOpen.cxx code,
in the output image all the pixels have the same value 3.4E38.

Is this a bug or I am doing something terribly wrong?


Thanks,

Alex
