Hi jfk,
I hope you could remember me. I commended your post of "burger face" a couple of weeks ago. I downloaded your app
and tried it on the device, to find out that it's really running very fast, which is the issue I want to ask about.
I am using opencv to do the hand detecting with N900. It could work. However, the problem is opencv's function such
as color segmetation, is very very expensive that the app running on the device is too slow to be shown as a demo.
I know you are not using opencv for the burgerface, but I hope you could share with me some skilful methods to
improve the speed of the app, if you have any.
It would be kind of you if you could offer me your email address, since I think we are doing some research very
similar. Anyway, I hope to keep contacted with you.
Cheers.

The thread Burgerface XD with 2 posts has been merged. The search box is in the upper right corner.
Since i am posting here, let me ask the OP a couple questions:
Did you make your own implementation of the Viola-Jones algorithm?
Did you compare the performance of multiple approaches?
What kind of framerate can this algorithm get?
Thanks for the interesting tech demo..

Classic example of arbitrary Nokia decision making. Couldn't just fallback to the no brainer of tagging with lat/lon if network isn't accessible, could you Nokia?

Yes, I implemented the Viola-Jones algorithm myself, including the trainer. It's pretty much the version of the algorithm they described in their original paper(s).
I compared it to a completely different approach which didn't work out that well. That is also why I selected Viola-Jones for the game. There is some additional information in the abstract of the thesis.
The framerate depends vastly on the window selection parameters and the cascade that is used. My cascade is pretty small. While it's quality is not that good, it can be executed very quickly. The demo, which can be downloaded, runs at around 20 FPS. It can be tuned to run faster or slower and thus I can either sacrifice detection rate or speed.

I got it working after installing the missing package. I'll have to try it at home, where the lighting's better and I won't look insane nice work though!
nice work though!
