With the Oscars fast approaching, the Actor Awards could be the next clue for who will go home with an Academy Award. But considering the Golden Globes and BAFTAs had some major differences, the Actor Awards are not easy to predict.

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.
