Kornel is also behind the DSSIM library (in Rust), which I've found useful for comparing images before and after compression.

Fun fact: I wrote DSSIM as a development tool specifically for pngquant, because I needed a way to measure improvements in dithering. Classic per-pixel algorithms only saw it as added noise.
