so what are those conditions? 
what are you trying to achieve, constraints, etc. 
I agree that infrared is the way to go so you don't interfere with projection lights, but haven't done this myself.

I'd get an infrared camera[1], make a simple threshold test, and get whatever is higher than the threshold to be white and the rest black and then go on from there...

?

Subject: Re: [PD] Getting Sihouette from GEM/pidip

I guess the trickiest part is not necessarily the software, but what the dancers are doing/wearing, the stability of your lighting conditions, the size of the space you're in, background noise, tracking strategy, and so on.

On the software side I guess (if I am getting you correctly) that you are looking to make say the dancer's chape white and the background black and project video onto the white elements only?

best,

J

Hello
 
Is there a way to get a Kinect like silhouette in GEM or pidip?
I would like to get the silhouettes of two dancers and project video into their silhouettes with a Video Camera getting the shape of the people without the need for depth or control.
Basically I guess a shape detector?
I am hoping someone has a motion detect/outline solution or a suggestion of how this may occur
 
Ideally I would like to then key out the silhouette and then syphon the output into Isadora for a Dance piece
 
Thanks in advance!
