I want to convert RGB colour images to greyscale. I know a number of ways to do this in Processing, but the algorithms are under the bonnet. I want to do the conversion AND know what I am doing! After some research ( Color-to-Grayscale: Does the Method Matter in Image Recognition? ), I have found the…

RGB in Processing already is gamma-corrected, so simply taking average of the 3 RGB components gives the Gleam metric. If we linearly interpolate over a range of values in Processing (say black-to-white, 0-255), we get an even change in the perceived brightness of each colour: a black-to-white grad…
