Tesseract OCR bindings for Node.js
Tesseract OCR bindings for Node.js.
I started developing of this module when had a need to have Tesseract working with Node.js. But found that
existing modules do call
tesseract command-line tool. And I have a need in fully customizable API. I started
from this article and now working with Tesseract 3.02 API
documentation. So soon will have much more things implemented! 😉
