This demo uses the CCV Javascript Face Detection Library.
To start run App.start() in your console.
You can also pass it a few different effects:
*App.start('glasses'); // Goofy Glasses example
*App.start('green'); // Green Screen effect (there is a hidden max and min sliders you can use to adjust the thresholds)
*App.start('hipster'); // simple pixel manipulation example
*App.start('blur'); // blur example
Requires a browser that supports getUserMedia (Opera Labs camera or Chrome Canary)
Start Google Chrome Canary with open -a Google\ Chrome\ Canary --args --enable-media-stream OR enable the flag in about:flags
