Re: A2-A1 scanner

You may want to try stitching multiple photos together using something like Hugin. There's a tutorial on this at http://hugin.sourceforge.net/tutorials/scans/en.shtml. It should also be able to fix lens distortions.
(Note that I haven't tried this myself yet though)

Re: E-book standard format

Just one other comment: I think reflowable layout will eventually die. They are here for now because (a) most ebook readers aren't large enough right now to handle a real page, and (b) web pages used to have to fit on small screens. What do you mean when you say "real page"? Sure, there can be seve...

Could this be eliminated by using a first surface mirror? (That's one with the reflective coating on the front of the glass instead of the back)

Re: Using a book scanner for non books (single sheets)?

I found a simple, portable design at http://kyleakoch.com/?p=48. Just add a piece of glass with safe edges to hold things flat.
It's for an iphone but should be simple to adapt for other cameras.

Since it has hocr output, http://jimgarrison.org/moz-hocr-edit/ might be useful too

Re: Brainstorming about portable book scanners.

For a portable scanner, having the platten upside down with the book lying on top, and the cameras underneath it might make for a more rigid structure, though it'd be more work to actually scan with. The SVG at http://www.tekstadventure.nl/branko/inverse_planetary_scanner.svg shows the idea. (Not my...

Re: unpaper and Hugin

Hmm, I don't have Photoshop so I'll just have to put up with it :( I believe that hugin can find the control points automatically but it needs a separate tool for that since the process is patented in some countries. I'll see what I can do with them once I actually get suitable pages :) PS. Welcome ...

unpaper and Hugin

Hi, I was wondering if anyone had used unpaper or hugin in their scanning workflow. I haven't tried them yet since I don't yet have a set of scans to work on (still don't yet have a scanner made) but was hoping someone else has experience with them. Unpaper http://unpaper.berlios.de/ is a tool for "...

Re: Post something about yourself here (The Hello Thread)

Hi, I'm Douglas and I've been interested in scanning my books for a long time due to the sheer space they take up and the fact that I've lost a few while moving. I've been put off it though by having to use a flatbed scanner which is why I'm so excited to read about this book scanner. Finally a way ...
