Abstract

A perceptual image compression codec exploits the characteristics of the human senses to minimize the perceivable quality loss of digital images under compression. Such a codec has an even higher value if the resulting codestreams are compatible to an existing standard, and are thus decodeable by all-day, existing applications. This work describes strategies how to implement perceptual coding in standardized environments, namely JPEG, JPEG 2000 and JPEG-XR.
