Caitlin,

I have put an example of basic labeling here:
http://www.vtk.org/Wiki/ITK/Examples/Images/ConnectedComponentImageFilter

<http://www.vtk.org/Wiki/ITK/Examples/Images/ConnectedComponentImageFilter>Once
you check out Gaetan's work, if you could add an example of how to do things
such as get the area of each component as well as delete components that
would be great!
