[vtkusers] Skeletonization 3D

[Andras Lasso]

VMTK (http://www.vmtk.org/) has a number of sophisticated VTK/ITK-based tools for skeletonization and centerline extraction, which work for complex, branching structures.

Hi,
I have used itkbinarythinningfilter for 3d skeletonization of vascular structures. So, for 3d data you can use the same filter.
Best,
Jaya

Subject: [vtkusers] Skeletonization 3D

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 ?
