Two things: 1. I like the natural feel it gives to images. 2. Easy to control. As much as it's super easy to cook up a matrix based error diffusion dither (like Floyd), there are a…

GIF rendering is a big use case. pngquant was a big comparison subject during development (it's a brilliant piece of work, and a mature tool that does a few things more than just q…

Yeah, good point. I'll definitely add an image showing the saliency map tradeoff. Regarding full examples, because some other projects seem to have cherry picked cases where they p…

Something that caught my eye is that it seemed to be a kind of "controlled" K-Means. One problem with K-means is that it's too sensitive to the initial state. You can run it multip…

Gamma aware operations happen in the C code. The python code you're referencing is just changing the scale of color intensities. What you shouldn't do is liberally add up sRGB colo…

Will take a look, thanks for sharing! This does not implement Wu v2 but a different method he published a year later though.
