SURF now for flash

What is SURF? It’s feature point detection. Just watch the video and you will understand it.

head tracking plus anaglyph

activate your webcam, mouse drag to draw a rectangle around your face -> test it

Hm maybe someday I actually start writing about the things I post, but not now. It’s beer time ;)

xbox360 body tracking

Would be really interesting to know how it works. Microsoft says it also works in complete darkness. Maybe they did somethin like this here:

Once again Tomek alias Og2t wrote a great flash demo. This time its about machine vision and just awesome. It’s motion based head / eyetracking with a lot of cool “hacks” like blob detection – histogram analysis – motion detection and more. Furthermore Tomek wants to provide a full framework.

This is a part of the whole video filter framework I am developing just now, the inspiration came from Joa Ebert’s Image Processing library (as far as I know, he’s cooking a complete rewrite). The full source code (including Pixel Bender kernels and examples) will be soon released on Google Code and will feature face/eye tracking/gestures and few other things (surprise!) A lot of people are very sceptic about the whole eye tracking idea, they don’t believe it’s precise enough to make any use of it – I will prove that it is, and it works! (just watch closely how it tracks my eyeballs on the video!)

I tried it, but I still prefer the camshift algorithm for face detection. Anyway: GREAT WORK!

SURF the next big thing

SURF is a computer vision technique which helps doing crazy things ;) Here is some footage showing whats possible. NOTE: no flash implementation yet ;) – I think it wouldn’t work -> performance
