Paper Abstract

This paper is a follow-up of a paperl given in the 1980 SPIE Conference, "Modern Utilization of Infrared Technology VI". A brief review is given of the earlier paper describing the test target, "BTP#4". This target is used in estimating the effects of various image chain processes, particularly displays on intage quality for image exploitation. The paper then presents an abstracted version of a study2, "Effects of CRT Display Variable and Image Analysis" conducted by D. Heagy and R. Holmes in 1982. This study supports the hypothesis that the BTP#4 target scores can be used to evaluate the quality of a monitor for presenting images for exploitation. A correlation of .74 was found between average BTP#4 scores and image interpretability quality ratings on a monitor calibrated and set to 12 operating characteristics. The paper concludes with some examples of BTP#4 applications and coimuents on its advantages and disadvantages.
