[vtkusers] Skeletonization 3D

[KitKat]

Hello,

I am looking for a tool able to extract the centerline (skeletonize) of a
structure in a 3D image, if possible without changing length.

What i am passing is a 500 * 500 * 500 vtkImageData composed of char either
at 0 or 1 (binary Image),
and i would like to thin it until I have a 1-voxel wide line structure
corresponding to the centerline, or median axis of the input image.
I know ITK has a thinningfilter, but after looking the source code i saw
that it only take 2D images.

Does someone know if such a tool exists and is compatible with VTK ?
