Android Question IN SEARCH OF OCR that actually works (Please)

[MitchBu]

I am starting to get desperate. I need OCR to scan books.

I tried the project at https://www.b4x.com/android/forum/threads/textrecognitionandroid-ocr.121018/#content but unfortunately, results are not consistent. Sometimes it works, other times nothing happens.

I downloaded this https://www.b4x.com/android/forum/threads/textrecognitionandroid-ocr.121018/ but the project requires ocrrest and I could not find it anywhere.

I then proceeded to download https://www.b4x.com/android/forum/threads/ocr-ocr-reader-complete.70659/.

Plenty of archives to download, but in the end, I get the error:

Maven artifact not found: androidx.annotation/annotation-experimental

I reinstalled the SDK following the instructions at https://www.b4x.com/b4a.html but still no joy. Seems what I downloaded following instructions no longer contain the required files.

Is there any OCR project that works out of the box ?

TIA

Does it need to happen locally on the device?

I don't care, really. I looked at the web service, but it still misses a library.

All I need is a B4A solution that actually works reliably.

Thank you, but I need that for B4A

Well, if it's a commercial solution I would probably throw up a VPS with Linux, running a simple service to do the ocr'ing and returning the text. Doing it like that would also mean you could somewhat easily improve the UX of your app by simply improving the server.

I'd probably start by installing Tesseract OCR https://blog.eldernode.com/install-and-use-tesseract-ocr-on-debian/
(Just a random article I found on the topic.)

What about taking a pic of each page and save them in a combined PDF? No miss reads....
