Conference article

Humans are the ultimate consumers of multimedia information; and effective system design requires a performance metric. While such metrics have been extensively studied for single-media perception for one or more decades; those for multimedia perception and use are still in their relative infancy. In this talk; I will focus on the devel-opment of single-media quality metrics for audio and visual information; and contrast it with the development of appropriate metrics for multimedia information. I will describe how humans perceive single-media information; how an understanding of perception has been incorportated into single-media coding and then quality measure-ment; and I will discuss the current state of understanding of multimedia perception as it has been applied to coding and quality measurement problems
