[Insight-users] Signed distance map?

[Zachary Pincus]

Is there a class in ITK that produces a signed distance map from an 
unsigned image (binary or otherwise)? The Danielsson map filter doesn't 
seem to do so, and the IsoContourDistanceImageFilter requires a signed 
level set image as an input.

It's easy enough to do this with two applications of the Danielsson 
filter on an image and its inverted pair, and subtract the results; I 
was just wondering if there is already a class to do this.

Thanks,
