WebJun 26, 2016 · Ordered dithering, rather than actively distributing error from one pixel to nearby ones 5, uses a simple index matrix to decide how the error gets distributed. It works like this: For each pixel from the source … Dithering is used in computer graphics to create the illusion of color depth in images on systems with a limited color palette. In a dithered image, colors that are not available in the palette are approximated by a diffusion of colored pixels from within the available palette. The human eye perceives the diffusion as a mixture of the colors within it (see color vision). Dithered images, particularly th…
