Software To Flatten a Photographed Book? 172

davidy writes "I have photographed some pages of a book for reading on my PDA. This is much faster than scanning and I don't have to carry the heavy books. However, the photographed books are not as nice: curved, skewed, and shadowed, as opposed to the much flatter, cleaner scanned books. I have searched for software that can flatten the pages for better reading on the PDA. So far I have come across Unpaper and Scan Tailor. Unpaper doesn't seem to have a windows GUI, and Scan Tailor doesn't unskew well. I remember reading about Google's technique of converting books to e-books with a camera and a laser overlay. Is there any home user software that can do a similar job without the need for a laser overlay or other sophisticated (and patented) technology?"

        Exactly, the document scanners used in libraries and archives are pretty much high resolution cameras on an adjustable stand. They don't work like flatbed desktop scanners where you have to squash the book flat on a plate of glass. As a result they are much faster, easier on the books and you get better quality scans for OCR processing.

            Flat bed scanners - well slow.

            AFAIK "flat bed scanner" simply means a scanner where you place the item to be scanned on a flat plane of glass to be scanned. The technology that actually does the scanning is irrelevant.

            In which case, the Xerox printer/scanner in my office does flat bed scanning in the blink of an eye. I ran it with the lid up once to prove to myself it wasn't just a camera - and sure enough a sensor bar whips across the page.

            Of course, it's not as practical for scanning bound books as the Google solution.

(or possibly a CCD arrangement, but usually they are in cheaper machines) But either way scanning a book on a 'flatbed' whereby the book has to be placed face down is a major chore. turning the page means lifting the book, turning the page, then turning the book back over and repositioning it etc etc. Even if the scan takes a blink all that manual work will make it tedious at

            Any decent mid-range multi-function copier will be able to feed its flatbed scanner from the input tray, meaning you can do 25+ pages at a time (depending on the model). And while it's not as fast as a drum scanner, it's not nearly as slow as you're implying here.

            Of course you have to destroy the book to use that option. But the equipment isn't hard to find: you likely have one in your office right now.

          standing back and zooming works great for low end cameras, upgrade to a real flash with a bounce or diffuser and power setting and you can do far more. Upgrade to a pair of light boxes and adjustable stand flashes and you can do everything.

      • Better yet, avoid zoom lenses and get a dedicated macro lens. Nearly every camera manufacturer makes at least one macro lens, and often two or three of different focal lengths. For books, a ~100mm macro works quite reasonably.

        The biggest problem is that a macro lens can be somewhat on the expensive side. If you want to stay cheap, Cosina makes a 100mm f/3.5 macro that looks and feels cheap, but has quite decent quality optics. This is widely available under various other names (Promaster, Quantaray, etc.

    As with most scanning and other things, you can save your self immense amounts of hassle time and money later, by spending a fraction of that time up front sorting out the 'input'. A bit of glass over the book, using a scanner, or even getting a friend to hold a book will mean that your source image will be much better to start with.

    Not everyone has 5-10mm thick peices of book sized glass lying around and it can be hard to take that sort of thing about the place in case of requiring to photo a book.

    There is software called Book restorer that does this removes curves 'geometrical correction' etc but it's pricy.

    i've tried un paper and it's pretty decent for what it does but it does have some limitations and it's not the most convenient to use.

    Deskewing, cropping, filling, etc etc are all easily done and I've even written imagemagick batch scripts in windows to do these things. The major trick is the curve removal.

    There's various ways you can determine the curve from a scanned image. If you have the edge of the page, you can calculate the movement required to straighten that, and then apply it to the whole image. You can use text based curve removal, similar to well known deskew algorithms for text, but takes into account different parts of the text may be 'more' skewed. i.e. rather than a rotational deskew a 'sliced' deskew. This needs to be done from the top to the middle and the bottom to the middle.

    If you have a good 'shape' of the page, and know the true size of the page, you can use a kind of morph operator to morph the corners back to th eright position and hope the image follows.

    Using a Greyscale/colour source will work better than a black and white source image in general.

    the other option is if the scanned / photoed page is actually of reasonaly good quality but if just a bit squint, then OCR it to a PDF and generate a new document using the OCR text, which will be pin sharp accurate, compress a lot better and be easier to use, although may not be ideal if there are too many errors.

Whatever you have read (and yea, I remember reading it too), it doesn't seem to actually be viable in practice. Sure, photographs are easier than scanning, particularly if you do it fast and cheap, but the result is poorer. If you can scan the book without damaging them I suggest you go back and do that.

      It never hurts to ask; if there were an easy magic software solution to do X, wouldn't you rather find out about it now, instead of after doing X?

      This guy didn't ask for 'magic' but for software to perform a conceptually simple task. He got two or three concrete examples above. There are nuttier posts on /. you can go and make fun of.
    • I know I'm probably getting modded Troll for this one; but there isn't always always an easy (magic!) software solution for every little thing. Sometimes you still have to put the work in if you want quality.

      Good thing we haven't had any enlightened lazy people in the past who actually solved problems similar to this. If they had, we'd be able to keep things cool without having to constantly refill our iceboxes, calculate things without having to do them by hand or mentally, or even have a machine write t

  • I went out and got one of the Planon Pen Scanners. Depending on what you want, they can go all the way to 600 dpi in color. Check out their web site. You can also get bargains on refurbished earlier models if you only need B&W and up to 200 dpi. http://www.planonstore.com/SearchResults.asp [planonstore.com]

      Yes. Forgot about these. They are pretty neat for just getting a couple of pages out a book. Scan quality is pretty good aswell
  • Not as fun as figuring out some massive kluge to do the job, but if it's a book that you can easily find used copies of just cut the binding off or remove the pages with a razor blade, and photograph them flat.
    Some of the ebook-torrent scans use that method. It destroys the book but makes for cleanly readable scans.

  • I would think you could correct for many of these issues by laying down several inches of foam, putting the book in place, and then pressing it down with a sheet of glass. Maybe with one more piece of foam to prop up the short side when you are at the beginning or end of the book. You know, kind of like what a scanner does...

    Of course, you'll still have to deal with lens effects like trapezoidal issues, or skew, but these I imagine are much easier to deal with than curl.

    Personally, I've switched to mostly
  • Load your raster files into OpenGL, apply them as a surface, then warp the surface until it appears flat to you. This is nothing more than what Google is doing automatically with lasers.
  • I'm sorry but this question is just ridiculous, or if not actually ridiculous then wasteful.

    Let me see if I understand this correctly: The author has photographed a selection of pages from a book that he wants to have available to read at his leisure. He doesn't want to carry the book around because it's too heavy, so what he wants to do, because the photographs aren't as pretty as scanned copies but scanned copies have artifacts of the scanning process, is to develop a home rig to scan the pages he's in

      Let me rephrase this in caveman terms:

      Caveman Gaor hears fellow caveman Ourgah has piled buffalo meat on few branches tied together.

      Ourgah asks if there be some invention he calls "weal" to fix under his brancard and carry meat around with no effort.

      Gaor says problem solved long time ago: just pick a big piece of leather, wrap the meat in it, carry it around on your shoulder. Problem solved. Anything else, waste of time.

      There be worse fates than carrying heavy bag on your shoulders.

  • A bit expensive, but an accurate pdf (jpg, etc.) to text OCR. Urban legend has it, this is old Russian software developed by the KGB, and back in the Yeltsin era there was a free loss-leader demo making the rounds for Macintosh. I doubt that's still available, but even at $400 a pop, ABBYY FineReader is pretty good stuff, IMHO.
  • So you took pictures of a book instead of scanning and now you want software to flatten the images like a scanner would? /facepalm
  • Visit freecycle/freegle and arrange a free scanner instead of using the wrong software to fix problems caused by using the wrong hardware. Seriously. You'll be glad you did. In fact, I have a redundant scanner here, which I'll gladly mail to you at no more than shipping costs.

FORTRAN is for pipe stress freaks and crystallography weenies.
