Re: How to convert a book to serchable pdf using open source software

As I use books in pdf format as a source for TTS, I compared also, how they are read by Moon Reader Pro + Ivona TTS engine on my Android phone. The main problem was that there are erroneous additional paragraph breaks in random places what makes the listening less fluent and comfortable. I need to ...

Re: How to convert a book to serchable pdf using open source software

Thanks! I am already using Scantailor for cropping, but am looking for software that would get rid of excess white space around text, and fingers, to edit my scans with before I start working with Scantailor.

Re: How to convert a book to serchable pdf using open source software

Does anyone know of useful software for cropping scans that runs on Mac Os? I think this thread answers more or less to your question: https://forum.diybookscanner.org/viewtopic.php?f=24&p=21785&sid=0ab34fa7fd0f5ee70fc925d0d99c4f21#p21785 In short, I would recommend Scan Tailor Advanced. It is able...

Re: How to crop and deskew pages using only free software?

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?

Re: djvu 1bit vs 8bits

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) ...

Re: How to crop and deskew pages using only free software?

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...

Re: Greetings from Kansas City, Missouri

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.

Re: Greetings from Kansas City, Missouri
