Simple head-tracking test 01

First head-tracking test: this is a simple program I wrote, to track the position of my head, as viewed by a webcam, assisted by two brightly colored markers.

Software: GNU/Linux, video4linux2 API.
Hardware: Logitech QuickCam 9000 Pro, goofy-looking glasses, bright yellow clothes pegs :)

If you want the code, you need to get it from my subversion repository: svn://nuclear.dnsalias.com/pub/compvis/cam_test
You will also need this library, which I wrote in the process: svn://nuclear.dnsalias.com/pub/libwcam

They sure are :)

That's cool but how'd you do it? where's the source? what kind of cam? why markers?

[nuclearthelab]

Hi, added the details on where you can get the source at the video info text. The camera is a Logitech QuickCam 9000 Pro.

I used the markers for two reasons:

1) It makes finding my head in the image much simpler

2) I need 2 points in the image for the calculations that I want to do in subsequent experiments.

By the way, the algorithm I came up with is pretty simple, and the source (I think) is not that hard to follow. Still, if you want an explanation of the algorithm, send me an email at nuclear -at- siggraph -dot- org

you seem smart. do you know if you can use markers for the general face trcking software. like if I was to put reflective dots or something on my face would it improve the face tracking on the logitechs software?

it's also funny :) e-Kerato :o

nice DIY though!
