[vtkusers] bone segmentation

[Summer Sun]

I don't think Mimics can do this automatically, it rely heavily on the
thresholding value you select, and the image data you provide. 

Here you get a whole vertebrae instead of one piece because your
thresholding range is too large and cannot make vertebrae pieces individual
from each other. 
But if you thresholding range is too small, you might lose some image
detail.

So to my knowledge, there's two option:
Option A is to erase extra pixels slice by slice near the connection of
vertebrae pieces to avoid misconnection. 
Option B is to shrink your thresholding, but that might lose some image
detail and make the generated model tough.

BTW, what's your problem with VTK here?
