# tracking.js

[![Build Status](http://img.shields.io/travis/eduardolundgren/tracking.js.svg?style=flat)](https://travis-ci.org/eduardolundgren/tracking.js)
[![DevDependencies Status](http://img.shields.io/david/dev/eduardolundgren/tracking.js.svg?style=flat)](https://david-dm.org/eduardolundgren/tracking.js#info=devDependencies)

The tracking.js library brings different computer vision algorithms and techniques into the browser environment. By using modern HTML5 specifications, we enable you to do real-time color tracking, face detection and much more — all that with a lightweight core (~7 KB) and intuitive interface.

However, the browser support may vary if you request the user's camera (which relies on [getUserMedia API](http://caniuse.com/#feat=stream)).

## Roadmap

- [ ] Optical flow
- [ ] Face recognition
- [ ] Pose estimation
- [ ] Faster keypoint descriptor (BRIEF)
- [ ] More trainings (Hand, car plate, etc)
