Colour tracking with the webcam in Flash

Something I wanted to do for a while. Track a colour using your webcam in Flash. I draw the webcam into Bitmapadata so I can play around with it. If you take the getColorBoundsRect straight from the raw bitmapdata it will be very hard to get something useful as you just have to many single pixels and colours to analise. So I implement a little trick that makes it better to analise. First I blur the video so it smooths the colours. Then I turn it into a 8 channel image.

After that I just layer a fresh video feed that isnt distorted on top and start drawing based on the colour and position.

Enjoy! You can grab the source here if you want.
