The core of the 10 lines code implements a simple method based on distance transform (rather than thinning based methods). The method is sensitive to the value of the user defined Thinness Parameter (TP). An alternative approach to 3D skeletonization that use the gradient and divergence of the distance transform is also given Reference: Ref 1) Nikhil Gagvani & Deborah Silver Tech.Rep.CAIP-TR-216 Parameter Controlled skeletonization of 3D Objects, June 1997 Download at : http://www.caip.rutgers.edu/~gagvani/skel/ Ref 2) Sylvain Bouix , Kaleem Siddiqi , Allen Tanneubaum Average Outward Flux via divergence & gradient http://sylvain.homelinux.org/~sylvain/research/projects/endoscopy/
