误差扩散是一种比较流行且效果较好的半色调方法，最早是由 Floyd-Steinberg 在 1975 年提出的，长时间以来，此方法一直被广泛应用。其基本思想是先按照确定的阈值量化图
像的像素，然后将量化误差以特定方式扩散到未处理的相邻像素上。这种方法需要进行
邻域处理，它能够为打印设备提供更高的半色调质量并且不引起网点增大，产生的半色
调图像无明显龟纹，视觉效果较好。-Error diffusion is a more popular and better halftone method was first proposed by the Floyd-Steinberg in 1975, a long time, this method has been widely used. The basic idea is to first determine a threshold pixel value according to the quantized image, and the quantization error diffusion in a particular way to the neighboring unprocessed pixels. This method requires neighborhood processing, it can provide a higher quality halftone printing equipment and does not cause dot gain, halftone image produced no obvious moire, visual effects better.
