I  can't  find  anything in the vtkCurvatures that allows You to set the local
reagion. I can't remeber where I came across a  curvature  filter  of  defined
local  reagions.  I  had  a  look in ITK but couldn't find it either. A have a
vague feeling that it was not called something with curvature in  its  name...
You could ask in the ITK mailinglist.

Sorry I can't be of any help here.
