thanks for the hint!
During the last hours I experimented with the Contour tracker. The results so far are much better than I expected!
But there are 2 big problems I don’t know how to deal with:
The glow sticks emit light to the bodies of the “users”. I think I can handle this using threshold of Contour. But the projection screen emits quite a lot of light, too. I’m afraid this is gonna be a major problem. (I’m gonna build a test setup tomorrow)
How can I recognize different colors? If I got it right, Contour converts the input into grayscale during processing?
