[ITK-users] possible to get a closest-point map from a distance map in ITK?

[Bradley Lowekamp]

Hello,

Sorry for the delay in following up with this!

Here is some information about how to create a module for your code:
http://insightsoftwareconsortium.github.io/ITKBarCamp-doc/ITK/ConstructITKModule/index.html

Please note that for a remote module it should not begin with the "ITK" prefix. Here is also some policy related info to:
http://www.itk.org/Wiki/ITK/Policy_and_Procedures_for_Adding_Remote_Modules

Please let us know if you need help. I think many people would appreciate getting easier access to these advanced morphology algorithms.

The label erode dilate filters aren't outputing the distance map, so they aren't exactly what you want, but they use the same kind of computation internally. Thus you could use them in conjunction with the parabolic distance transforms to get labels and distances.

Is there something like this implemented already in ITK? I would like to use something like this to produce a spatially varying distance threshold.
