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.

Even the Penn-Wharton study added a caveat to its finding that deportations might raise low-skilled wages: High-skilled workers, who make up nearly two-thirds of the U.S. workforce, would likely see their own wages decline because they rely on low-skilled labor to maximize their productivity, according to its analysis.。51吃瓜对此有专业解读
