Machines are looking for Michael Jackson

Today passes my 5th year of living and working in the UK... feeling in sort of a nostalgic/festive mood, did some cool VJing last nite and decided to spend semi-hangovery afternoon doing some (softcore) flashcoding. I got some good feedback and suggestions (thanks you know who) to my recent Terminator Salvation "machine vision" experiment and decided to explore that area a bit further.

This time I've managed to add "the real face tracking" ported from OpenCV by Masakazu "Mash" Ohtsuka (with some great optimizations by Quasimondo) to my video processing framework (codename HiSlope) which should be hopefully released within a couple of weeks (still need to do some important/major refactoring). Follow me on for updates.

So I was looking for some perfect video to use for testing... couldn't think of anything really. Then suddenly the spirit of Michael Jackson (RIP) came to me and whispered into my ear: "Black or white?" – and it was all clear then :)

Enough words, click the image to sing along.

I found this video particularly challenging – with loads of head banging and different races (skin tones, facial hair etc.) – which actually makes a perfect source material for testing.

And again, I am really surprised by the final result – it's still not the fastest (I am getting 20 FPS in browser and about 35 FPS in standalone projector) but the main task is achieved.

The filters' settings were optimized for the video, so if you switch to the webcam mode you probably won't get your eyes detected (there's still a bit of work for me to do on it – that's why I am not releasing the sources yet), but do try to play with sliders, especially with HSBC (no, not the bank, it's Hue, Saturation, Brightness, Contrast) – enable it by clicking the checkbox on the left) and Eye Finder – enable debug and adjust blur and fuziness.

So, where's Michael? He's wandering somewhere in that black puma's outfit, fighting with racism. Watch out!
