Interesting, although my method runs at up to about 2000 pages per hour,
mostly unattended rather than having to do something physical every 2
pages. Of course, I destroy the binding, but usually with an electronic
version, I don't care much for the original anyway.
A few months ago, I was just thinking that I needed software to easily
dewarp images of things that I 'scan' with my cameras, which I've been
doing for over 5 years now. These guys have a package and my favorite
scanner software also has that capability now.
