I found that there was no structure tensor filter in ITK; perhaps
someone could point one out, it was a while since I used ITK. But, in
the meantime I hand-rolled my own (plain code, not filter):

  http://github.com/JDonner/gabbleduck

in gaussian.cpp and pipeline.cpp.

It's really too messy to actually recommend to anyone but, it exists
if you want to look at it. The names of things should be reasonable at
least.
