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.
