Recognize text in images using OCR (optical character recognition) techniques.

Based on node-tesseract.

Installation  

This package has a hard dependency on Tesseract. You must have Tesseract installed on your laptop/server to use it.

Installing Tesseract

For Homebrew users, installing Tesseract is quick and easy:

brew install tesseract --with-all-languages

You can find installation instructions for various platforms on the Tesseract project site.

Tesseract Version

This probably works with any version of Tesseract v3.01 or higher, but I have only tested extensively with:

machinepack-ocr: ∑ tesseract -v
tesseract 3.04.01
leptonica-1.73
 libjpeg 8d : libpng 1.6.24 : libtiff 4.0.6 : zlib 1.2.5

Installing this machinepack

Now you can install the machinepack in your project:

$ npm install machinepack-ocr
