More Than Just Quite OK – Data Compression Nerds Hate This One Trick (eh22)

How one guy in his bedroom (kind of) beat all of PNG's combined multi-decade effort in one year, and why that's strange. For over two decades, PNG has been the state-of-the-art for lossless image compression. But the Quite Okay Image Format is an emerging low-complexity alternative that offers a different perspective on data compression. This is a talk about PNG, JPEG, QOI, and how more complex doesn't always mean better. Also included: lots of juicy data compression nerdery, including many basics, and an unsurprisingly large amount of maths.
