That Looks Oddly Familiar — Jan Stępień
Perceptual hashing is a fascinating technique of summarising media files. It has little in common with cryptographic hashes such as SHA1. Two input files which look similar will end up having different cryptographic yet similar perceptual hashes. And by similar, we mean having most bits set the same way.

In this talk we'll combine pHash and a BK-tree to efficiently search through metric spaces of perceptual hashes. We will use Rust to implement a simple command line tool. It will ...
