Ha ha, I've just realized that the easiest way to implement "page fixe" in the quick and dirty style I often prefer is to write a script to slam the ScanTailor project file and then reload the project. Don't need to touch the code. We'll see how workable this turns out to be in practice...

Some good advice & suggestions in your post there Spamsickle, thanks. I'm interested if anyone else finds it best to uncheck the despeckle option? If, as I suspect, most do so then perhaps the default could be for off in the next version, might save a bit of grumbling here when I forget to untick it....

Cheers, P.

Tulon has said he's planning to make the despeckle option less aggressive, but I'll probably still uncheck it. I honestly haven't seen any "speckles" left by ScanTailor in the final product without it, and wouldn't mind if this was unchecked by default.

Getting despeckling right is on the top of my priority list. I am going to make it adjustable, and the default will be much less aggressive.
When Scan Tailor asks you to enter DPIs manually, never enter arbitrary values. The video tutorial shows how to estimate the real DPI.

Hi Tulon, sounds good, I've not tried photographing & processing any books with foxing so I guess that's where the despeckling option comes into its own? Like Spamsickle I've not yet run into a situation where it's ever been needed, I do have some older spotty books here (an otherwise lovely 1st edition of Wuthering Heights comes to mind) so will perhaps give that a go to see what happens.

Cheers, P.

Despeckling is important for books printed on low quality paper. Most of the books printed in USSR are like that.

Hi!

I have downloaded and compiled version 0.9.7.2. However I cant find Rob's work.
I took pictures from free hand, so didnt build a book scanner (yet), so I would like to
try out the dewarping feature.

Im compiling right now the git version. Can somebody write some pointers how can I activate the
dewarping feature? Is it included in 0.9.7.2?

Best regards,
Laszlo

UPDATE: I already compiled and tried out the git version. Still cant find it.
I looked at the git history, but only 3 commits were made after the RELEASE_0_9_7_2 tag.

Also I cant find Rob's commit in the history either.
Is it added?

Can I reproduce the same result what is shown on the news page?:

Ok, I reread the whole thread one more time. Looks like Rob never committed his change. There is the published java code, and some promising pictures.

Rob: could you post a patch, I would like to try it out. And I would like to see it in scantailor sourcecode, even if its in a very rough stage.

I was trying out some possible improvements before committing it, but I'll commit it in its current form today.
