Here is the build: http://depositfiles.com/files/r15711m4c
There are still some rough edges, but automatic dewarping itself seems to work well.
Note: don't use this build - it crashes on pages with little or no text. There is a newer build later in this thread.
P.S: Up to date source code is in Git.

Scan Tailor experimental doesn't output 96 DPI images. It's just what your software shows when DPI information is missing. Usually what you get is input DPI times the resolution enhancement factor.
Re: First build with automatic dewarping
Tulon, this is amazing. The quality of this feature is unsurpassed, I don't know how you do it. I've been trying this out on some scans I've been saving for a while, expectantly awaiting this mile stone, and I've had a lot of success with them. You will probably be getting a lot of these types of messages in the near future, and I don't feel entitled to any response, however if this is useful to you I thought I'd share one of the tricky images I have, that you are likely to have difficulty with in the future. As you can see in the following picture:
There is some difficulty when the end of the last line of text is indented, this causes the image to dewarp into a trapeziod. Anyway, thanks for the fantastic work, this thing is really robust. I hope the above image is helpful to you, and not a pain in the butt. Let me know if you want the source image. Thanks again.Re: First build with automatic dewarping
Normally that's not a problem, provided the vertical boundaries got detected correctly. On the next tab in debugging mode, you would see those blue lines extended up to the vertical boundaries. If the vertical boundaries got detected incorrectly, or if it still somehow produces a trapezoid, I can take a look if you provide me with the source scan.Shaknum wrote:There is some difficulty when the end of the last line of text is indented, this causes the image to dewarp into a trapeziod.
BTW, multicolumn text is not supported by this algorithm. The reason it works in this particular case is that text lines in your columns are aligned and close together.

Re: First build with automatic dewarping
Oh my god! That's a nice present for us Tulon. Thank you so much.
Re: First build with automatic dewarping
Re-he-heally awesome!
Will just wait for someone to build a Mac version.
Thanks a ton, Tulon.

Re: First build with automatic dewarping
Indeed. Very awesome. I too hope that a binary Mac version comes along somehow. I had some success building it on my own, but somehow the jpeg import was broken then.
Re: First build with automatic dewarping
Ah, great!
I thought that you had given up completing this.
Thanks for this and have a happy new year.
