[Insight-users] 3D skeleton/centerline

[Ruben Schilling]

Hi Ajay,

I actually want to do the same thing and have some questions and some  
answers. I can share how I approach this problem at the minute. I use  
the Danielsson Distance map from ITK to calculate a distance  
transform. You would then have to extract local maxima from it, that  
correspond to your skeleton. This approach requires preprocessing to  
fill wholes, which can be done in itk via the iterative fill holes  
filter.

My question:

I would like to have 1 voxel thin lines or even better: a discrete  
graph extracted.

Can anyone tell me (us) how to do this?

Best
Ruben
