Question about the method

[billtubbs]

This is a great project thanks. I'm trying to figure out if I could have used it on a recent project.

I'm not raising an issue, more of a question about understanding the method:

1. Does the identification of the LEDs happen in closed-loop with the webcam or is the excitation sequence generated first, then fed to the LEDs, and then the resulting webcam video analysed after-the-fact?

2. Is the final output the simply the physical co-ordinates of the LEDs (x, y) or does it also determine the mapping of intensity-values to webcam brightness?

I tried to figure out the answer myself but wasn't clear from the description.
Thanks.
