Re: Best free OCR SW
When it comes to easy-to-use cross-platform OCR software, I would also look at gImageReader (https://github.com/manisandro/gImageReader). It is a front-end to Tesseract, but is really intuitive to use and has a wide range of options.

Re: Confirm single camera post-processing workflow, please!
Sorry for the delay in responding, and I hope it is still of some use. The post-processing steps you describe are similar to mine. I also use a single camera scanner. The main difference is that you take the left and right pages separately, whereas I take them in sequential order, so there is no nee...

Re: How to convert a book to serchable pdf using open source software
Well, actually I am not able to say, what is wrong. I expect that my lack of abilities is reason for that. When I try to install 'archive-hocr-tools' I have this error message: $ python3 -m pip install setup.py Defaulting to user installation because normal site-packages is not writeable ERROR: Coul...

Re: How to convert a book to serchable pdf using open source software
Nice to see that. I sought for free implementation of MRC and apparently here it is. Unfortunately, I was not able to test the program due to some dependency issues. Nevertheless, it looks very promising. Thank you for sharing info about this software with me.

Re: LED lamps 'Warm' or 'Cold' light - Does it matter?
I would like to suggest rather "neutral" white (4600K) instead of "warm" or "cold" white light source. That is definitely less problematic and gives good results with standard white balance algorithms in smartphone cameras. I tried also "warm" white LEDs (2700...

Re: Combining Split output into PDF
What I don't understand, better, I don't know is how to achieve the 2 passages after scantailor: PDF size 50% JPEG -G4 and PDF at 150dpi scaling (I am on linux). Can you explain me what have I to do? What do you mean by 'PDF size 50% JPEG -G4'? Do you want to have JPEG compression applied to color ...

Re: Combining Split output into PDF
Adobe Acrobat in more recent versions does a good job with Scan Tailor output and creates such 'optimized' pdf files, where color and b&w content is segmented and compressed separately. The result seems to me to be similar to Abbyy FineReader MRC compression model.

Re: How to convert a book to serchable pdf using open source software
Actually, each book created by me using the described method has a colored front cover and back cover. Contents between covers are binarized (B&W). There may be added pictures in color, but it would be necessary to manually convert them to appropriate format and turn into pdf, and afterwards ins...

Re: output dimensions ratio
In the bottom part, near the right-hand corner you have information on dimensions of the image. Width and height may be adjusted at the 'Margins' stage. You may change units by selecting 'Tools' and 'Units'.

Re: How to convert a book to serchable pdf using open source software
My bad. I was convinced that OCRmyPDF supports jbig2 but apparently this applies only to regular pdfs.
