[Insight-users] ultimate erode set (erode up to object centres)

[lynx.abraxas at freenet.de]

Hello!


I just found the SignedDanielssonDistanceMapFilter. Since I want to apply a euclidian distance transform on the "ultimate eroded set" I'm not sure if the SignedDanielssonDistanceMapFilter produces the same result already in on go. Does anyone know if that is correct?
In total I want to create a small program that separates and labels pores/particles by watersheds.

Thanks for any help or hints
