[jitter] Re: 2d Position Tracking in Low Light

thanks yair,

I'm thinking to just simply try getting some IR lEDs and filtering out visible light using the developed color film trick mentioned often in other posts.

Can anyone recommend some really strong IR LEDs that would be good for tracking at a distance in low light? 

Also, is there any real advantage to using reflective tape and bathing the stage in IR light over simply using an IR LED on the performer? I don't imagine much other conflicting IR sources at the performance, there will just be the projection screen and the performer visible in almost total darkness. The only other light will come from whatever we project which I imagine is not going to interfere much in the IR range.

Any other advice? I am thinking cv.jit.track should do the job nicely enough.
