As navigator, Lovell took with him a sextant to take star readings - in case the computers failed and they had to find their own way home.
This time, before we perturb the input image, we take the value given by the threshold matrix and divide it by , where is the number of levels for each colour component. As a result, each pixel is perturbed just enough to cover the minimal distance between two colours in the palette.
