[vtkusers] vtkVolume centroid

[Massinissa Bandou]

Hello everyone!

I have a CT volume and I want to extract the position of 3 landmarks (first
picture) to perform a landmark registration with another volume. My first
idea was to surround the landmarks by 3 boxwidgets (second picture) and
extract the 3 volumes of interest using boxwidgets bounds. 
My question is how can I get the position of the *maximum intensity* of
those volumes?

All ideas or suggestions are welcomed!!! thank you for your help!
