Ordered dithering 算法
WebApr 26, 2024 · You should have only one image: you modify the input grey-value image, setting each pixel to either 0 or 1, and spreading the difference with the original value to the next pixels still to be processed. That means that your algorithm should only read from Floyd, not from image or pic. And Floyd should be a copy of pic, the original image. WebFloyd–Steinberg dithering is an image dithering algorithm first published in 1976 by Robert W. Floyd and Louis Steinberg. It is commonly used by image manipulation software, for example when an image is converted into GIF format that …

Then … 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.
