Abstract
Described herein is one or more implementations that produce a new representation of a digital good (such as an image) in a new defined representation domain. In particular, the representations in this new domain are based upon matrix invariants. More particularly still, the specific matrix invariants described herein include non-negative matrix factorizations (NMF).
