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

[Richard Beare]

I've written a set of label erosion and dilation filters that might do what
you're after. I've also got some spatially varying morphology filters, but
have't put them on the insight journal. 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.

I can provide more details about the spatially variant stuff if it is of
interest. Note that it only works with binary images, and simply weights
the input image.
