Ordered dithering
WebMay 25, 2011 · The main difference between dither vs ordered dither is the way of the quantisation error spreading. Dither - the quantisation error is spread (in Floyd-Steinberg) … WebDec 28, 2012 · Dithering is an attempt to solve this problem. Dithering works by approximating unavailable colors with available colors, by mixing and matching available colors in a way that mimicks unavailable ones. As an example, here is the cube image once again reduced to the colors of a theoretical old PC - only this time, dithering has been …

WebOrdered Dither • For a constant gray level patch, turn the pixel “on”in a specified order. • This creates the perception of continuous variations of gray. • An N ×N index matrix specifies what order to use. I2(i,j)= 1 2 3 0 • Pixels are turned on in the following order. http://www.infogalactic.com/info/Ordered_dithering
WebA generalisation of the dithering technique we just saw that uses a certain family of patterns is called ordered dithering. It is based on a dither matrix such as the following one: Using the matrix coefficients as threshold values yield the following results for black, white and three shades of grey (0.25, 0.5 and 0.75): 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 • Ancin, Hakan; Bhattacharjya, Anoop K.; Shu, Joseph S.
