Given known and new signatures of different types of nuclear
facilities, it should be easy to automatically identify objects that
match these signatures using existing GRASS functionality.

Maybe of interest is also a GRASS module for object recognition,
i.segment. It should be possible to filter the objects identified by
i.segment with known signatures.
