these compression algorithms could halve our image file sizes (but we don't use them) #SoMEpi

an explanation of the source coding theorem, arithmetic coding, and asymmetric numeral systems
this was my entry into #SoMEpi. this video can get pretty confusing, so don't worry if it takes some rewatches to understand. if i had more time i would've made it better....but anyway i hadn't seen many videos on this so i hope it is a helpful introduction
