Real Time Feature Point Tracking in AS3

Its a bit late, so instead of posting a long informative post about how feature point tracking works I thought I'd just upload some of my results from this evening. I think its quite exciting stuff. The image shows feature point tracking working relatively well on my pupils, and also on other facial features (the last two images). I am very pleased with the result.

A related project I have also been working on this evening is optical flow which I am close to getting 
working, here is a preview of what is to come:

Both methods are used in tracking objects in moving images and have been implemented in real time. I will post sample movies and some explanations shortly so you can play around with them yourself.


  1. HI,
    nice work. i'm searching some source code to implement in an application for my rovio to follow my face. Could you send the source code ?
    I'm searching for face detection and emotiv detection.
    Thanks !

  2. Hi Vince,

    A good open source project to look at is OpenCV, I'm not sure how useful flash would be for your rovio.

    Take a look at:
