The WebRTC getUserMedia API is available on the Nightly and Aurora channels of Firefox right now and Tim has done a couple of <a href="http://timtaubert.de/blog/2012/10/building-a-live-green-screen-with-getusermedia-and-mediastreams/">great</a> <a href="http://timtaubert.de/blog/2012/10/getusermedia-part-2-building-an-eyetoy-like-mini-game/">demos</a> of using JavaScript to process the media stream. That got me interested and after a little playing around I remembered learning the basics of convolution image filters so I thought I’d give it a try. The <a href="https://www.oxymoronical.com/experiments/convolution/">result is a sorta ugly-looking UI</a> that lets you build your own image filters to apply to the video coming off your webcam. There are a few pre-defined filter matrices there to get you started and it’s interesting to see what effects you can get. Remember that you need to enable <em>media.navigator.enabled</em> in about:config to make it work.</p>
