StarWars: Realtime Chromakey + light saber

Hi everyone,
I’m responsible to create a mini science exposition, and I had come with an idea, but I don’t know if it is possible…

I was thinking on having a Star Wars simulator. People would be captured with a blue/green screen, holding a red stick and see themselfs (on a display) inside a starwars movie holding a light saber. Everything in realtime.

Jitter would capture the camera image, remove the blue/green screen background, replace it with a starwars movie file, detect the red stick, appy some image processing in that area(blur,brightness,etc) to simulate a light saber, and output the result to the monitor.

I worked some years ago with MAX, but I never worked with Jitter. Do you think this is possible? It is very complicated?

Sounds like it is definitly possible if you don’t mind having some errors with red jackets and blue jeans. The keying part is peanuts, but have a look at http://www.iamas.ac.jp/~jovan02/cv/ for the light saber. Btw for the best keying, consider narrow band ultra-reflective material (expensive but effective).

Greets,

Oh, but.. what is a light saber without the characteristic light saber sound? ;)

why would one need to bother with cv? just use jit.chromakey again to extract the lightsaber, only set the mode to 1. This should be cheaper on the processor.
