Text recognition (OCR) with Jitter and opencv?

March 22, 2014 | 11:26 am

Hi folks!

Do you know if there is a possibility to extract text from live cameras? Optical character recognition (or text recognition) with openCV, maybe cv.jit?

Thank you very much for any tips you may have!

Possible? Well… you know… :)

Probable? Not likely. Getting jitter to recognize certain blobs as characters would be possible – but to do that with a screen full of characters of varying shapes and font styles, all positioned at random – in real time? I just don’t see it happening on this platform.

Maybe there is something that could be done in java? You might also consider a separate application that can stream the OCR results via your network and use OSC in Max to grab the data in real time.

Good luck with your project.

I would agree with Metamax: I don’t think this is achievable with CV tools on real-time video. You could try running Tesseract or similar, grabbing/saving frames with Jitter and do OCR via command-line?

Thank you, guys! Yeap I guess I am stuck with other programs which I don’t have a clue about.

I found this and hopefully it will do the job: https://www.youtube.com/watch?v=Kjdu8SjEtG0
