Image Compression with Neural Networks
jpeg 2000 had about a 20% reduction in size over typical jpeg, while producing virtually no blocking artifacts, 16 years ago[1].  Almost no one uses it, though.  Now in 2016 we are using neural networks to get a similar reduction, except the dog's snout looks blurry, and with a process that I assume is much more resource intensive. It's interesting for sure, but if people didn't care about jp2, they would have to be drinking some serious AI Kool-aid to want something like this.[1]:  https://en.m.wikipedia.org/wiki/JPEG_2000
