<p class="MsoNormal">Hi, <br>
I have used itkbinarythinningfilter for 3d skeletonization of vascular structures. So, for 3d data you can use the same filter.

<p class="MsoNormal"><span style="font-size:11.0pt">Hello,<br>
<br>
I am looking for a tool able to extract the centerline (skeletonize) of a<br>
structure in a 3D image, if possible without changing length.<br>
<br>
What i am passing is a 500 * 500 * 500 vtkImageData composed of char either<br>
at 0 or 1 (binary Image),<br>
and i would like to thin it until I have a 1-voxel wide line structure<br>
corresponding to the centerline, or median axis of the input image.<br>
I know ITK has a thinningfilter, but after looking the source code i saw<br>
that it only take 2D images.<br>
<br>
Does someone know if such a tool exists and is compatible with VTK ?<br>
<br>
<br>
