I know that the conversion from RGB to grayscale is based on the wighted average method as shown in the following equation:

gray = .299*redChannel + .587*greenChannel + .114*blueChannel

What I need to know is the math behind this equation and the coefficients.

Thank you for the help.

What do you mean? That is the math. Do you mean you want to know how the coefficients were arrived at?

Exactly. How are they derived? What mathematical procedure is used and from where are they originated?
