.. _example_tvtk_segmentation:
Tvtk segmentation example
--------------------------------------------
Using VTK to assemble a pipeline for segmenting MRI images. This example
shows how to insert well-controled custom VTK filters in Mayavi.
This example downloads an MRI scan, turns it into a 3D numpy array,
applies a segmentation procedure made of VTK filters to extract the
gray-matter/white-matter boundary.
The segmentation algorithm used here is very naive and should, of course,
not be used as an example of segmentation.
