Abstract
One- and two-way communication with digital compressed visual signals is now an integral part of the daily life of millions. Such commonplace use has been realized by decades of advances in visual signal compression. The design of effective, efficient compression and transmission strategies for visual signals may benefit from the proper incorporation of Human Visual System (HVS) characteristics. This paper overviews the psychophysics and engineering that enables this pervasiveness. It presents a short history of advances in perceptual visual signal compression, describes perceptual models and how they are embedded into systems for compression and transmission, both with and without current compression standards.
