[Insight-users] diameter of segmented object

[Benjamin King]

Hi all,

I want to compute the diameter of a segmented voxel object. As a first 
approach, I took the binarized image and subtracted an eroded version to 
get the boundary points. Then I compute the distance of each pair of voxels 
and take the maximum.
I need I much faster way (i.e. not O(N^2)) to do this.

Any suggestion is much appreciated,
  Benjamin
