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

[Bradley Lowekamp]

Richard,

You have some nice additional morphological filters in those repositories. I have been meaning to give them a try.

Given that you have Insight Journal articles for them, have you considered making them more readily available to the community by adding and converting them into Remote modules for ITK?

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.
