[Insight-users] question on "DanielssonDistanceMapImageFilter": works in N-D

[Luis Ibanez]

Hi Sebastian,

The DanielssonDistanceMap filter works in N-D images.
(as almost all  ITK filters).

However you have to instantiate the filter for the appropiate
dimension of the image you want to process. That is, you have
to make a decision at compile time.

I assume that you are using the example:

       DanielssonDistanceMapImageFilter.cxx

available in

      Insight/Examples/Filtering

If you want to run this example on 3D data, simply go to
lines 281-282

  typedef itk::Image< InputPixelType,  2 >   InputImageType;
  typedef itk::Image< OutputPixelType, 2 >   OutputImageType;

and make them

  typedef itk::Image< InputPixelType,  3 >   InputImageType;
  typedef itk::Image< OutputPixelType, 3 >   OutputImageType;

Recompile, and run

---

This filter is described in the SoftwareGuide
http://www . itk . org/ItkSoftwareGuide . pdf
under section 5.6 "Distance Map".



Please let us know if you encounter any problem.


Regards,


    Luis
