Hi all,
I am wondering if anybody can recommend a duplex-capable multi-sheet (automatic) scanner to be used under OpenSuSE Linux. By multi-page I mean something with a feeder that can scan in a whole stack of paper.
Thanks.
Boris.
Just last week a weekly news email I get talked about getting a new office scanner. Below is what they wrote. I looked it up on the 'net and it seems to work with Linux. Check it out,
Hope this helps,

################## A PRODUCT RECOMMENDATION. I needed a new scanner. I asked a few people, including a guy I know who owns a business employing 75 people but has no filing cabinets, what is a good scanner to computerize receipts and such? The response was unanimous: the Fujitsu ScanSnap. It's amazing: a contract and a check? Scans the differing page sizes without a hitch, scans fronts and backs at the same time, discards any blank pages, creates a PDF file, and then does an OCR (optical character recognition) pass on the file so that you can search within it. And it comes with all the software you need, too. The thing is so amazing that if you put a page in upside down, it will usually detect that and flip it around for you! And it detects the rare occasions when it misfeeds (e.g., pulls more than one page through at a time.) A 5-page scan, front AND back, only takes about 15 seconds (plus OCR time; that process runs in the background). I'm completely blown away by it, and my bookkeeper just loves it, too, since I now know where everything is, and can e-mail stuff to her easily. It's a tad pricey ($470), but cheaper at Amazon ($420 as of this writing). This thing gets my highest recommendation. http://ThisIsTrue.com/d-scansnap
Ugh: I just clicked the link to check it before sending this out, and Amazon has raised their price to $465 since Monday's Premium edition! Sheesh. Check Newegg.com, then: it's $409 there right now, though that's plus shipping (free on Amazon). Still, that's the best price I can find right now.

I see the phrase "all the software you need" and red flags go up. How much of all this is done my 'the device' and how much is done by software on a [Windows?] host? Does this device work with LINUX/openSUSE? I'm curious because I've looked at several such things and they are always tethered to a Windows 200x server, usually with M$-SQL as well. So the cost of the-device is almost irrelevant.

If I were scanning my magazine collections, with photos, I would use 600dpi minimum, so that I could print a page later as good as the original.

I agree, and 600 dpi won't get you a particularly faithful reproduction. Phototypsetting equipment realizes 2400 DPI, typically.

I'm a little curious what Google and ACM (to name only two) use to digitize print collections. The results render well and, what's much more impressive are OCR-ed quite well, too. ACM's entire digital library (most of which predates digital originals) is searchable even when the original had to be scanned and OCR-ed.

Yep. Good OCR for me is almost impossible to achieve, but these big chaps seems to have it solved. Djvu format, by the way, can store B/W for text, color for photos, and text for the OCR, all in the same file and for each page. In theory, at least: with the open tools we have that's almost impossible to get. The better tools are not open.

Interesting. From Wikipedia, the free encyclopedia In computer software, Tesseract is a free optical character recognition engine. It was originally developed as proprietary software at Hewlett-Packard between 1985 until 1995. After ten years without any development taking place, Hewlett Packard and UNLV released it as open source in 2005. Tesseract is currently developed by Google and released under the Apache License, Version 2.0.[2][3][1] Tesseract is considered one of the most accurate free software OCR engines currently available.[3][4] The current version of Tesseract is 2.03, released April 22, 2008.[5] ... Tesseract is an OCR engine, and it does not have a graphical user interface. It runs from the command line, and may be called with the command:[7] tesseract image.tif output [options] Tesseract handles image files in TIFF format (with filename extension .tif);[7] other file formats need to be converted to TIFF before being submitted to Tesseract. Tesseract does not support layout analysis, which means that it cannot interpret multi-column text, images, or equations, and in these cases will produce a garbled text output.[3] http://en.wikipedia.org/wiki/Tesseract_(software) You could add how do you installed it, in suse. Looking on webpin, I just see unofficial packages: cer@nimrodel:~> webpin tesseract 2 results (2 packages) found for "tesseract" in openSUSE_110 * tesseract-ocr: An OCR engine - 20080718svn178 [BS::home:/jnweiger] * tesseract-ocr-devel: Libraries and Header Files to Develop with Tesseract - 20080718svn178 [BS::home:/jnweiger] cer@nimrodel:~> The wikipedia mentions also OCRopus, used by Google Book Search, using Tesseract as a plugin: OCRopus is a free document analysis and OCR system released under the Apache License, Version 2.0 with a very modular design through the use of plugins. These plugins allow OCRopus to swap out components easily. OCRopus is currently developed under the lead of Thomas Breuel from the German Research Centre for Artificial Intelligence in Kaiserslautern, Germany and is sponsored by Google. OCRopus is developed for Linux; however, users have reported success with OCRopus on Mac OS X and an application called TakOCR[1] has been developed that installs OCRopus on Mac OS X and provides a simple droplet interface. It is also CLI only. - -- Cheers, Carlos E.
