I know that this might be a duplicate of this question but that was over 3 years ago and some things might have changed. I need an OCR library for Windows mobile (6.1) to detect characters (one up to 3 words) from camera’s photos.
I am kind of aware of that it would involve HUGE amount of coding if I would have to write it on my own so I would really appreciate finding some kind of libraries that would help me do this.
I would prefer C# libraries but C++ will be also good (if nothing else is to be found).
EDIT
Ok so I have managed to sort this out partially: I have downloaded project from Alex Karpus’ site where he presents his job with openCV on Windows Mobile (and iPhone). I didn’t try to port openCV to Windows Mobile but I did manage (and it took me quite significant amount of time) to successfully deploy openCV onto my Windows Mobile phone. Now I am looking for some hints how can I do the OCR while I already have the openCV on the phone :).
If you have any suggestion please post it either here on in my question about Artificial Neural Networks’ OCR link
There isn’t one built-in. Quite a few .NET OCR libraries are available commercially, but you’d probably need to talk to the developers about whether they can compile a proper version for you, because the PC assembly won’t work.
You could also try to port Tesseract to C# and compile it for the phone, but that would be a non-trivial undertaking if someone else hasn’t already started it.
I think you could also use one of several websites that let you upload an image and send you back an OCR’ed data. Try http://www.ocrsdk.com, it is a cloud based OCR SDK recently launched by ABBYY. It’s now in closed beta so it’s completely free to use.
