Principled Methods for Color Dithering Based on Models of the Human Visual System (1992)
The problem of representing gray-level images on a binary display device is variously known as "dithering" or "half toning." Previous approaches to the problem have started with an algorithm, usually one which is easily computed, and then judged the results by visual comparison with the competing algorithms. An alternative approach begins by trying to characterize computationally what makes one image visually "better" than another. It is then possible in principle to find the halftone which is optimal in terms of visual quality, and the problem becomes one of searching for the optimum. This approach has been applied to monochrome images with encouraging results. Here we apply this approach to color.
