WebThe technique described so far is also known as ordered dithering since clusters of dots are used where the order of the dots is given by the dither matrix and is not changed during execution of the dithering algorithm. 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
