Page layout analysis is on my list of things I'd like to get to one day. Given 
the length of the list, it won't be in the next year.

I did do a bit of poking around with algorithms to do this, and ocropus 
appeared to have some reasonably good code that we might be able to reuse 
given some process separation (since it is incompatibly licensed). If re-use 
doesn't work, there are still a lot of good algorithms that might be suitable 
that are linked off the ocropus site. Suggest you start with 

At least Okular has a page layout wishlist item (to allow smarter selection 
during cut-n-paste of a region) so maybe there is a way to provide this as a 
general facility to other users.
