DIY Book Scanner

I do not expect that Scan Tailor is able to provide perfect or very good results without some manual corrections. It is universal tool but it seems you would need something more customized and tailor made. Maybe something based on OpenCV?

PDF in Abbyy. djvu with djvu small mod. I do not have much experience with Abbyy Finereader. However I would guess is that in case of 1 bit pictures there is jbig2 compression applied and no MRC compression is necessary. In case of grayscale images, algorithms do separation of foreground (letters) ...

some screenshots in order to make my above comments more clear.

Scan Tailor Advanced has the 'crop' function. After 'Splitting' and 'Deskew' stages there is 'Page Box' in select content. There is rectangular selection (orange lines) that should cover the cropped area. You should apply 'Page Box' manual mode and 'Content Box' auto. Apply it separately to even and...

What software do you used for creating pdf and djvu files?

Hi Brandon,

Many thanks for sharing effects of your work with all. I'm convinced that not only me but many other people keep fingers crossed for implementation of something similar to Adobe ClearScan.

Cheers.

Hello Brandon,
Effects of binarization presented in form of two screenshots at your Github repository are really impressive. Do you have plans to add some interface to your algorithm for users that want to use it as standalone program?

I have a question though: is it possible to somehow correct OCR output from Tesseract other than editing the pdf in Acrobat (I don't feel like paying monthly for that)? I've been trying to do OCR with gImageReader on Linux. It uses Tesseract and you can preview txt file, but to actually correct it,...

Hmm, don't think it's this that is the cause - Ubuntu package for ImageMagick has never had jpeg2000 in my memory and pdfbeads has been falling back to JPEG quite happily for years (iunluding in at least but not limited to 18.04, 17.10, 17.04 and 16.04). The hard crash is new in Ubuntu 18.10. There...

Another version of Ubuntu, another breakage in PDFbeads and dependencies. The standard ImageMagick version in Ubuntu’s repositories doesn’t support jpeg2000 compression. You need to compile newer version of ImageMagick to have this (it may be tricky as there are other dependencies that need to be r...
