[Insight-users] distances in x-y-z independently

[Xabier Artaechevarria Artieda]

Hi all,
I am looking for a filter that returns the distance from each pixel to  
an object in each axis independently.
In other words, for each pixel, it should look at all the pixels with  
same X and return the minimum distance in that dimension. The same for  
Y and for Z, if the image is 3D.
I have looked at DanielssonDistanceMapImageFilter but it returns a  
vectorial image with the distance to the closest object point, instead  
of considering each dimension independently.
Is there any filter that does what I am looking for or should I develop one?
Thanks in advance.
Best,
Xabi
