    "abstract": "The perceptual impact of various high definition television (HDTV) systems is evaluated using just-noticeable difference analysis. The major conclusion of this analysis is that foreseeable cameras and displays do not permit effective utilization of luminance bandwidths beyond roughly 10 MHz in a 4×3 aspect ratio format. Furthermore, by exploiting the eye's reduced temporal capabilities for both high spatial-frequency luminance and for chrominance information, and by utilizing subcarrier quadrature modulation, a HDTV system seems possible whose total bandwidth is less than 10 MHz in a 5×3 format.",

Carlson received the BS degree in Physics, with honors, from Worcester Polytechnic Institute in 1967, He received the MS and PhD degrees from Rutgers University in 1969 and 1972, respectively. His thesis work was primarily concerned with problems in coherent optics. Since joining the Technical Staff of RCA Laboratories, Princeton, NJ, in 1973, Dr. Carlson's research has centered on visual processing in both human and machine visual systems. This includes basic research in psychophysics, signal processing, imaging analysis and artificial intelligence, with applications to NTSC television, high-definition television, and robotic vision. In 1982, he became Head of Advanced Image Processing Research at RCA Laboratories. Dr. Carlson was an NDEA Title IV Fellow and is a member of Sigma Xi, Tau Beta Pi, the Optical Society of America, the Society for Information Display (SID), and the Association for Research Vision and Ophthalmology. He is a member of the SMPTE Committee on HDTV. He was recently a Special Editor of an issue of the SID Proceedings on “Recent Advances in Visual Information Processing.” Dr. Carlson has won two RCA Achievement Awards for his research in vision and image processing. He has published or presented over 50 technical reports and publications and holds four US. patents, with many more pending, in hisfields of interest.",

Bergen received the B.A. degree in mathematics and psychology from the University of California, Berkeley, in 1975 and the Ph.D. in biophysics and theoretical biology from the University of Chicago, Chicago, IL, in 1981. His work concerns the quantitative analysis of information processing in the human visual system. At the University of Chicago he was involved in the development of a model of the spatial and temporal processing that occurs in the early stages of the system. From 1981 to 1982 he was with Bell Laboratories, Murray Hill, NJ. His work concentrates on the effect of visual system structure on the extraction of information from a visual image. He is currently with RCA Laboratories in Princeton, NJ. His current work includes basic studies of visual perception as well as perceptual considerations for design of imaging systems.",
