I have just download a code about detecting and tracking RGB colour. I saw they set the colour threshold like red Thresh = 0.25, green Thresh = 0.3 So I dont understand about these values. Why he chooses 0.25, what if I set it is 0.99. What gonna happend? Thanks for your help.

@Vu Trinh: Seriously? If you do not mention, which code you are using, how could we guess, what the parameters are doing? Please explain the details.

If you change the threshold(s), I would guess that you're going to be tracking an object of a different color, or an object of a different size.
