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. A number of other algorithms are also known; they generally involve changes in … See more • Matlab implementation of various dithering methods • anim8gdx, Java implementation of various (mostly ordered) dithering methods See more The ordered dithering algorithm renders the image normally, but for each pixel, it offsets its color value with a corresponding value from the threshold map according to its location, causing the pixel's value to be quantized to a different color if it exceeds … See more • Ancin, Hakan; Bhattacharjya, Anoop K.; Shu, Joseph S.

Web随机抖动算法随机产生一组模板方阵数列,随机数的产生期间在图像的最小灰度和最大灰度之间。有序抖动算法是人为地设置一些模板值进行匹配操作,主要有分散性抖动算法(Disperse Dither)和聚集型离散算法(cluster Dith神两种。分散型以Bayer有序抖动算法为代表。 Web有一种不用提升分辨率就能在原图上使用dither算法的方法,也就是我们今天要讲的方法。 假设使用上面所说的8x8的块,此方法不用把每个像素变大64倍,而是直接在原图上进行这种划分,将原图划分为若干8x8的块,对原图的每个像素,和相应块中的阈值做比较 ... phoenix asx
