WebbIntroduction——Dithering 是什么 Dither is an intentionally applied form of noise used to randomize quantization error, preventing large-scale patterns such as color banding in images. 从Wiki的解释可以看出，Dithering所要处理的问题是信号量化误差引起的大尺度pattern，使用的手段是噪声。不严谨的说，量化是指把一个连续信号映射到离散信号的 …

Floyd–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 is restricted to a maximum of 256 colors. WebbThe algorithm is characterized by noticeable crosshatch patterns in the result. For more information see Ordered dithering on Wikipedia. Random, Random covariant. These methods of dithering use randomization of the pixel values to reduce the number of colors. the uk\\u0027s flag

In addition, a low-frequency noise signal was applied as a sinusoid signal (magnitude: 3, and frequency: 5 Hz), and a random noise was also applied to the base signal. For comparison, a third-order Butterworth filter with a cut-off frequency of 10 Hz was adopted as the LPF. the uk\u0027s prime minister
