cheque-ocr Build Status

Optical Character Recognition for cheques using the MICR Code standard.

Input Output 
{
  confidence: '86.748',
  numbers: {
    transit: '00502',
    institution: '010',
    account: '705555'
  }
}

Installation

  • Required: node v6.8.0 or greater
  • Recommended: n and avn
  • To install, run npm install cheque-ocr [TODO]

Usage

var chequeOCR = require('cheque-ocr'),
    fs = require('fs');

var image = fs.readFileSync('/path/to/image.jpg');
chequeOCR(image, function(err, result) {
  console.log(err, result);
});

For a demo, run node examples/basic.js.

How it works

  1. [TODO] Normalize orientation of cheque image.
  2. Determine region of interest (ROI) where the MICR Code exists.
  3. Within ROI, use Tesseract to convert MICR Code to text.
