Mulkiya-OCR is an experiment app, I’ve used Tesseract Open Source OCR engine to read text from images(for example mulkiya image) so that data input process can be automated and accurate as much as possible. The code is open source at github.

For those who are not familiar with word “Mulkiya”. It’s an arabic word which means vehicle registration card or vehicle ownership certificate.

Getting Started

  • Install tesseract-ocr open source OCR engine
  • git clone [email protected]:minhajkk/mulkiya-ocr.git clone repo from github
  • npm install Install the dependencies in the local node_modules folder.
  • bower instalk Install client side bower dependencies.
  • npm start to run the application.

The application is built upon nodejs and angularjs frameworks, find bellow more details about stack.

Server Side Dependencies (NPM)

  • multer Multer is a node.js middleware for handling multipart/form-data.
  • expressjs Web application framework.
  • node-tesseract A simple wrapper for the Tesseract OCR package for node.js

Client Side Dependencies (Bower)

  • angularjs Superheroic JavaScript MVW Framework.
  • ui-routr For robust routing provider.
  • angular-material For amazing material design support.
  • ng-file-upload Amazing angularjs file uploading directive additionally allows mobile devices to capture using camera.


Mulkiya-ocr is deployed on heroku @ https://mulkiya-ocr.herokuapp.com/. There’s a great step by step tutorial provided by heroku for deploying a Node.js app in minutes have a look in case you’re interested in using heroku.

Deployment was the main challenge for this application since I had to install tesseract-ocr on server before deployment but thanks for heroku’s multiple buildpack support It was great experiment using heroku multiple buildpacks on this app.

What’s next?

  1. Manipulate image before processing for example increase/reduce brightness/contrast so text can be extracted easily.
  2. Develop algorithm’s to extract right information from mulkiya such as model, car, year etc etc
