This, while interesting, is not IC related. You'd have better luck at an OCR
forum, esp one with and API like I believe LEAD has:


At any rate, any good OCR and a perl script to parse the data should work,
but any solution won't be 100% accurate. You may want to use "zone
detection", two zones being for registration, and the rest for answers, then
use imagemagik to see whats going on with the pixels (if that's possible) to
determine what's filled in and what's not. I wouldn't leave it to
recognition of text and numbers though, too ify.
