Perceptual coding: History, Applications & Standards

Perceptual coding is a method of lossy data compression that exploits the limitations of human sensory system in order to reduce data size. It is widely applied in audio, image and video compression standards, where certain details are removed or simplified because they are unlikely to be noticed under regular listening or viewing conditions.
