Available in PDF, EPUB and Kindle. Book excerpt: 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).

This book was released on 1967 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: An evaluation was made of the separate screening of aerial photos prior to interpretation as a technique for improving performance in the quick-time extraction of information from imagery under varying conditions of frame overlap and image quality. Rolls of positive transparencies were interpreted by 48 interpreters under two conditions: In one condition, the photos had been screened by experienced interpreters; in the other, interpreters used normal Hot Report techniques combining frame selection and target identification in one process. Zero overlap and 50 percent overlap and two levels of image quality were represented in the imagery. On the first trial, half the subjects interpreted preselected imagery, half used regular techniques; on the second trial, procedures were reversed for the two groups. Interpreter performance was evaluated in terms of screening efficiency, accuracy and completeness of interpretation, time and rate of interpretation, and errors. The separate screening procedure added significantly to interpretation time. Overlapping imagery added significantly to interpretation time without increasing accuracy or completeness. The slight difference in image quality introduced did not seriously affect processing time. Accuracy of both screening and interpretation was lower with the lower quality imagery. Screening was more seriously affected than was interpretation. On the basis of evidence, screening cannot be recommended as a useful procedure in rapid interpretation. (Author).

Book excerpt: The Surveillance Systems research program of the U.S. Army Behavioral Science Research Laboratory has as its objective the production of scientific data bearing on the extraction of information from surveillance displays and the efficient storage, retrieval, and transmission of this information within an advanced computerized image interpretation facility. The present technical research report summarizes in integrated fashion the major problem areas, the rationale of BESRL's approach to their solution, and the general course of research studies completed or in progress in the surveillance areas of manned systems experimentation. The research effort is conducted within the following Work Units: (1) Interpreter Techniques--The determination of interpreter techniques in a surveillance facility; (2) Image Interpretation Displays--Influence of displays on image interpreter performance; (3) Intelligence Systems--Intelligence information processing systems; (4) Image Systems--Information processing in advanced image interpretation systems. Studies of the Surveillance Systems research programs conducted by the Support Systems Research Division of BESRL have resulted in findings which are applicable in optimizing human component performance in existing systems and in providing systems developers with information useful in design specifications for future systems.

Download or read book Color in Electronic Displays written by Heino Widdel and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the product of Research Study Group (RSG) 13 on "Human Engineering Evaluation on the Use of Colour in Electronic Displays," of Panel 8, "Defence Applications of Human and Biomedical Sciences," of the NATO Defence Research Group. RSG 13 was chaired by Heino Widdel (Germany) and consisted of Jeffrey Grossman (United States), Jean-Pierre Menu (France), Giampaolo Noja (Italy, point of contact), David Post (United States), and Jan Walraven (Netherlands). Initially, Christopher Gibson (United Kingdom) and Sharon McFaddon (Canada) participated also. Most of these representatives served previously on the NATO program committee that produced Proceedings of a Workshop on Colour Coded vs. Monochrome Displays (edited by Christopher Gibson and published by the Royal Aircraft Establishment, Farnborough, England) in 1984. RSG 13 can be regarded as a descendent of that program committee. RSG 13 was formed in 1987 for the purpose of developing and distributing guidance regarding the use of color on electronic displays. During our first meeting, we discussed the fact that, although there is a tremendous amount of information available concerning color vision, color perception, colorimetry, and color displays-much of it relevant to display design-it is scattered across numerous texts, journals, conference proceedings, and technical reports. We decided that we could fulfill the RSG's purpose best by producing a book that consolidates and summarizes this information, emphasizing those aspects that are most applicable to display design.

Download or read book Visual Psychophysics written by Zhong-Lin Lu and published by MIT Press. This book was released on 2013-10-11 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive treatment of the skills and techniques needed for visual psychophysics, from basic tools to sophisticated data analysis. Vision is one of the most active areas in biomedical research, and visual psychophysical techniques are a foundational methodology for this research enterprise. Visual psychophysics, which studies the relationship between the physical world and human behavior, is a classical field of study that has widespread applications in modern vision science. Bridging the gap between theory and practice, this textbook provides a comprehensive treatment of visual psychophysics, teaching not only basic techniques but also sophisticated data analysis methodologies and theoretical approaches. It begins with practical information about setting up a vision lab and goes on to discuss the creation, manipulation, and display of visual images; timing and integration of displays with measurements of brain activities and other relevant techniques; experimental designs; estimation of behavioral functions; and examples of psychophysics in applied and clinical settings. The book's treatment of experimental designs presents the most commonly used psychophysical paradigms, theory-driven psychophysical experiments, and the analysis of these procedures in a signal-detection theory framework. The book discusses the theoretical underpinnings of data analysis and scientific interpretation, presenting data analysis techniques that include model fitting, model comparison, and a general framework for optimized adaptive testing methods. It includes many sample programs in Matlab with functions from Psychtoolbox, a free toolbox for real-time experimental control. Once students and researchers have mastered the material in this book, they will have the skills to apply visual psychophysics to cutting-edge vision science.
