[Insight-users] Signed distance map?

[Luis Ibanez]

Hi Zach,

This has been a common request,
There is a bug entry in the database regarding the
need for implementing a signed distance function

http://www.itk.org/Bug/bug.php?op=show&bugid=737&pos=5

The idea is to do it by running twice a Danielsson
distance filter.


You may want to vote for this bug in order to
increase its priority.


   Regards,


     Luis
