[Insight-users] Re: Signed distance map

[Luis Ibanez]

Hi Lucas,

You are right, the DanielssonDistanceMap generates a
non-signed distatnce.

For computing a signed distance you may use the
ReinitializeLevelSetImageFilter
http://www.itk.org/Insight/Doxygen/html/classitk_1_1ReinitializeLevelSetImageFilter.html

OR...

You could use two Danielsson distance map filters.
One taking as input the mask of your object, and a
the other taking as input the negation of the mask.
Then combining the outputs of the two Danielsson
distance map image filters.


Regards,


      Luis
