SURF now for flash

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

Eugene wrote a great outstanding BRILLIANT version for Flash (FP 10). You can find more infos here

head tracking plus anaglyph

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

and here are the credits:

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:

Face / Mimik tracking in AS3

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!

multi object motion / direction tracking

eugene wrote a great demo on object motion / direction tracking.

Ar in 2d – video and demo

Here is the promised video to my augmented reality in 2d post


You can test it here

Description:

  1. Click on color
  2. Click on other color
  3. Tracking starts – white circles
  4. Try catching the black rect edges
  5. enjoy

Sourcecode:

  • This time just on email and (at this time) not for commercial use
  • download here

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
