scantailor-advanced VS naps2

There's also https://scantailor.org/ (and a maintained fork at https://github.com/4lex4/scantailor-advanced ) which semi-automates unwarping and other corrective tasks in scanned books.

ScanTailor Advanced (downloads are in the sidebar, labeled as "Releases") is a little more complex. It takes a folder of images and performs a series of steps to produce good book scans, though it might be useful for your purpose as well. The first step after importing images is to split them up, and ScanTailor does this by looking for straight lines that might indicate a gap between pages. Now, I don't know if this will handle any more than two pictures per image, but it will at least handle doubles. ScanTailor will also attempt to automatically deskew pictures, and then there are a few steps that you'll need to take to make your pictures come out nicely.

My preferred method is to take pictures of all the pages of the book (Open Camera has a nice option to take a new picture every n seconds), optionally touch them up with ScanTailor (automated), and then turn all the images to a PDF using NAPS2 (which will OCR the text as it goes in).

Next is the cleanup. Scan Tailor is the best game in town for this, but it's a dead project. Instead, there are two forks that have picked up where the original developers left off. Scan Tailor Advanced is my current fork of choice, though Scan Tailor Universal tries to add new usability features. For whatever reason, only Advanced makes full use of my CPU, so it's several times faster than Universal for the time being.

No problem. https://github.com/4lex4/scantailor-advanced/releases

If you are interested in more ways to treat a scan, ScanTailor is definitely an option. I am using a fork called ScanTailor Advanced which is available under GPL-3.0 on GitHub. With this tool you can also crop your images and apply options like threshold or posterization to improve readability while further reducing the file size.

I use a £15 arm with a vice grip for my phone from Amazon, copy the files to my laptop and then run a bash for-loop of the tesseract CLI over the resultant files.

I use https://github.com/4lex4/scantailor-advanced to deskew the images and generate the PDF.

It isn't perfect but my purposes are more around research than publication, so, YMMV!

If you have a HP Printer there is scanning software program (Free and Open source) called Not Another PDF Scanner. https://www.naps2.com/ It's simple to use and works really good with HP printers unlike the software that comes with the printers. Everyone who wants to scan with a HP printers needs this software.

Brother DCP-L2550DW here. One of the cheapest b/w multifunction devices with automatic document feeder and reasonable print and scan performance. Works like a charm on Linux, Windows, Android, and IOS.

I am using it with [NAPS2](https://www.naps2.com/), which is brilliantly simple, multi-platform, free, and open-source.

If you want to add page, remove page, split, merge, reorder, re-orient all or individual pages, ... May I recommend the glorious NAPS2 [1] ?

It's meant as a scanning tool but works just fine without scanning just drag and drop a pdf on it.

It doesn't do in-page editing or annotation, it's "one layer above" that.

Tips: For PDF management/splitting/rotation/cropping ect before import: NAPS2 is a good tool (Windows, Linux, Mac). It also support ocr (same as paperless-ngx use) https://www.naps2.com/

To scan to image files, use the included Windows Fax & Scan app. To scan to PDF files, use NAPS2.

The software I use is: https://www.naps2.com/

If you are on windows this can scan and OCR using tesseract. https://www.naps2.com/

Try https://www.naps2.com/ It has Arabic support. Once installed with OCR settings, if you drap pdf onto app, it does OCR.
