What does it say when you do:
Code:
sudo gainroot
apt-get install libsdl-ttf2.0-0

Nice to see that there is use for the front camera ;-). I'm curious, what face detection method are you using, Viola-Jones?

really impressed with it. a great well done to you!
it does open the way to other tools that can use face detection :)

would also to know how you detect things :D (would be useful for the back camera too :)

But, superb little game and very innovative.

Yes, that's the one. It's a pretty nice algorithm, though it has its limitations. I also threw some optimizations into the mix.

Thanks! :)

Using the front or back camera is not a big difference. That's just a matter of changing the device name. Theoretically, you could turn BurgerFace into a two-player game by having one player hold the N900 and the other move his head. ;)

haha good idea :) - Yeah i figured out the gstreamer front v back early today in my healthcheck app... :) - i'm only capturing stills though, not sure how to send the video to a qlabel though (using python and QT).

I wouldn't know anything about that. :) I'm working on a lower level using V4L2 and SDL.

To install the package manually, you need to have rootsh installed which is in extras. Open X Term and type:
Code:
sudo gainroot
dpkg -i MyDocs/.documents/burgerface_0.1-1_armel.deb
Or maybe (I'm not sure of the path right now):
Code:
sudo gainroot
dpkg -i MyDocs/burgerface_0.1-1_armel.deb

Also see this thread.
ey!



Not for now. I think that I'll prepare a proper version with highscore stuff after completing my thesis. :)

Sorted thanks yes not got the lastest firmware but this worked. Great use of the front camera off to do the survey

Great stuff! At least now I could put good use of my head. :D Just had a couple of issues where my head seems to get lost easily or unable to track. I'm in a pretty well lit room with sunshine though.

But thanks for this demo!

Yeah, my experiments have also shown that the lighting can be "too" good. The detection doesn't work that well when the light comes from behind you or from the side so that your face is not evenly illuminated.
