Canvas element used to do basic image-processing on an image. Can a JS port of NumPy be far behind? What about the effects on expectations for javascript from users and engine writers? *Mind buzzes*

"In this way, reCAPTCHA’s unique technology improves the process that converts scanned images into plain text, known as Optical Character Recognition (OCR). This technology also powers large scale text scanning projects like Google Books and Google News Archive Search. Having the text version of documents is important because plain text can be searched, easily rendered on mobile devices and displayed to visually impaired users. So we'll be applying the technology within Google not only to increase fraud and spam protection for Google products but also to improve our books and newspaper scanning process. That's why we're excited to welcome the reCAPTCHA team to Google, and we're committed to delivering the same high level of performance that websites using reCAPTCHA have come to expect. Improving the availability and accessibility of all the information on the Internet is really important to us, so we're looking forward to advancing this technology with the reCAPTCHA team."

I know I'm late to the game commenting on this one, but damn this kind of thing pisses me off. Can't we have just one thing that is cool on the internet without it getting acquired by Google or Yahoo? I'm not as anti-google as most, but all of a sudden reCAPTCHA feels exploitative. Brewster Kahle, where is the alternative for archive.org?

Scan Tailor is an interactive post-processing tool for scanned pages. It performs operations such as page splitting, deskewing, adding/removing borders, and others. You give it raw scans, and you get pages ready to be printed or assembled into a PDF or DJVU file. Scanning, optical character recognition, and assembling multi-page documents are out of scope of this project. [09wk47]

Windows/Linux: Tired of fiddling with scanned pages to remove borders, correct alignment, and otherwise prettify them before storing or emailing them? Then Scan Tailor could be right up your alley. This free app splits two-page scans into single documents, converts text to black and white without disturbing images, and cleans stray specks off pages. Scan Tailor even gets rid of that pesky shadow down the center of a two-page scan that occurs when you lay an open book face down on a scanner.
