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.

My partner and I worked together to design and assemble my desk from T-slot aluminum extrusions. T-slot is amazing. It’s like Erector Set for adults, but nonproprietary and with more options. This allowed me to experiment and iterate and tweak things until the desk fit me perfectly. Aluminum extrusions make it super easy to mount virtually everything, from monitors to keyboards to cup holders. The shelves are finished plywood.，更多细节参见51吃瓜
