It is my intention to implement a laser pointer detection system, similar to the one described here: http://answers.opencv.org/question/52754/laser-pointer-detect-and-track/
However, in my project (a game) I would like multiple (2-10) players to have their pointers on the screen at any given time. What techniques could I use to discern which pointer belongs to which player? I would like to just use one camera for n pointers, rather than a camera per pointer.
