WebJun 26, 2016 · Dithering is easiest to conceptualize when thinking about a single channel (greyscale) image being quantized to a single bit (black and white). In the case of having two colours in your palette, each pixel from … Ordered dithering is an image dithering algorithm. It is commonly used to display a continuous image on a display of smaller color depth. For example, Microsoft Windows uses it in 16-color graphics modes. The algorithm is characterized by noticeable crosshatch patterns in the result. See more The algorithm reduces the number of colors by applying a threshold map M to the pixels displayed, causing some pixels to change color, depending on the distance of the original color from the available color … See more The above thresholding matrix approach describes the Bayer family of ordered dithering algorithms.
