I found one dumb free win (I mistakenly used value receivers on a utility function called on a large struct thousands of times a frame). But the rest of the speedups I found took more effort.
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. Since the entire palette is evenly distributed across colour space, we only need to modify the range of perturbation along each axis. The dithering equation then becomes:
