SMPTE Engineering Committee Report: Bibliography: Psychophysics of Image Evaluation

Abstract

Comparative subjective judgments of image quality from carefully structured tests provide one essential criterion for evaluating the many possible procedures for achieving electronic or electronic-assisted production and post-production. With the many systems of image processing involved, and with the need for comparison with the appropriate photographic systems, each variant offers the potential for its own type of defects, aliasings, and distortions of the "original." Whilc subjective judgments may also be employed for studies within a single system, this bibliography conccntrates upon procedures found applicable for the broader case when images from a diversity of processes are to be compared.A Task Group on Psychophysics was established by the Working Group on High Definition Electronic Production (WGHDEP) in 1982 to assist a group of scientists in the field in focusing upon the problems specific to the WGHDEP. Similar study groups have been formed by the FCC, ATSC, EBU, and CCIR. While the members of the WGHDEP Task Group are now continuing their work as members of the other groups, this bibliography reflects their work and concentrates upon the objectives of concern to the WGHDEP. I t documents the most relevant published presentations of the techniques and procedures for developing, conducting, and evaluating subjective tests of the quality parameters for diverse image presentations. It is thus concerned with comparative evaluations of im-Contribution received from the SMI'W Working Group on I ligli Definition Electronic l'rodiiction. Frederick J. Kolb.

Picture quality measurement based on block visibility in discrete cosine transform coded video sequences

“…However this kind of global measure of degradation does not correlate well with subjective rating. [3][4][5][6] Then it would be of great interest to develop an objective measure which exhibits a high degree of correlation with subjective assessment. To accomplish this, one must account for the psychophysical properties of the human visual system ͑HVS͒.…”
