[vtkusers] SIFT legal issues

[Bill Lorensen]

David,

According to wikipedia:http://en.wikipedia.org/wiki/Scale-invariant_feature_transform

 "The algorithm is patented in the US; the owner is the University of
British Columbia.".

 If this is true then we cannot include it in VTK or ITK.

And you should be careful how you use it in your own work. You may be
violating the patent.
