Abstract : The Image Interpretation Task, USAPRO, is responsive to a continuing ACSI requirement for development of techniques to improve utilization and performance of image interpreters. The present study initiates research into the physical qualities of imagery in terms of their potential for intelligence extraction. Sets of photos differing in scale, sharpness, and contrast were ranked by interpreters in terms of ''usefulness for intelligence information extraction''. Relationships of physical variables and interpreter rankings to information output were examined; dimensionality of image quality judgments was further explored through application of multidimensional scaling techniques. Two dimensions-scale and sharpness--were clearly identifiable in judgments of photo quality; two other factors associated with contrast and photo content were also indicated. Findings point to a promising utility of judgment in assessing image quality and to improved intelligence output by interpreters through use of image quality scales. (Author)
