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 perform very well, I wanted to go for a "try it out yourself" approach, at least for now. Maybe in the future I'll add a proper showcase. Thanks for the feedback :)
take a look at my demo [1]. i'd love to see the same set of images quantized with your thing.
the quant frog [2] is interesting since it has an artificial single pixel line at the top with a ton of colors to trip quantizers up.
