CV/OCR Library

Hi,

Does anybody know if there is an OCR or some CV library available for Pharo?

I would like to make an experiment with recognizing the content of
some fixed size form, and of course I prefer to do it with Smalltalk
whenever possible.

Regards!

Hi Esteban,

I know that Sean D has wrapped the Tesseract OCR library:

I know that there is an openCV binding by https://twitter.com/DmitryMatveev

You have a binding in GT too.

Hi,

Indeed, we have an integration for OpenCV here:

Esteban, I did a little work getting it working in Pharo 8 and adding an
example. Check out `Tesseract class>>#exampleHOCR` and LMK if it fits your
needs. If not, PRs are welcome ;-) FYI I'm developing in Gtoolkit at the
moment, so I'm not sure if the Morphic part (e.g. inspector extensions)
still works, but I think it should. What's been implemented so far in the
Bloc equivalent works in latest GT, but is WIP.
