WebOrdered ditheringis an image ditheringalgorithm. It is commonly used by programs that need to provide continuous image of higher colors on a display of less color depth. For example, Microsoft Windowsuses it in 16-color graphics modes. It is easily distinguished by its noticeable crosshatch patterns. WebFloyd-Steinberg Dithering The Floyd-Steinberg dithering algorithm is an example of an error-diffusion technique. The aim is to use simple threshold dithering on each pixel, but to accurately account for the errors in brightness it induces. As a simple motivating example, consider a 50% gray image (an image with
