WebFeb 8, 2011 · Thresholding is usually what dithering is trying to improve upon. Details in large grey areas are lost and sharp edges appear where they may have been smooth gradients in the original image. In terms of random dithering we can think of the threshold result as “random” dithering where the “random” number is always 0.5. Random WebMatlab.

WebOrdered dithering is an image dithering algorithm. 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 Windows uses it in 16-color graphics modes. It is easily distinguished by its noticeable crosshatch patterns.
