Another way to approach dithering is to analyse the input image in order to make informed decisions about how best to perturb pixel values prior to quantisation. Error-diffusion dithering does this by sequentially taking the quantisation error for the current pixel (the difference between the input value and the quantised value) and distributing it to surrounding pixels in variable proportions according to a diffusion kernel . The result is that input pixel values are perturbed just enough to compensate for the error introduced by previous pixels.
曾国藩、王船山意见，乍见则骇人听闻，然而细思乃有至理深义。其实古人对此早有评论：“衣食分人，曹刿指为小惠；乘舆济人，孟子谓非政要。”义仓、社仓等等与各位的捐赠一样，只是花钱做了衣食分人及乘舆济人的一般的、简单的、浅层次的事。如同用药治病，只是敷在表皮，略缓病痛，没有用在病灶上。
