"unpaper" is free software and is actually pretty good at finding
margins automatically. Maybe that could be called optionally? It would
just be used to find margins and provide the coordinates to docview.

Also I have some code to call "opencv" to find lens dust in an Emacs
image in my "Emsane" package on github.

Just some random feedback for you.
