Johnson's criteria, or the Johnson criteria, created by John B. Johnson, describe both image- and frequency-domain approaches to analyzing the ability of observers to perform visual tasks using image intensifier technology. It was an important breakthrough in understanding the performance of visual devices that it would provide the basis guiding the development of future systems. Using Johnson's criteria, many predictive models for sensor technology have been developed that predict the performance of sensor systems under different environmental and operational conditions.
Famous quotes containing the words johnson and/or criteria:
“So different are the colours of life, as we look forward to the future, or backward to the past; and so different the opinions and sentiments which this contrariety of appearance naturally produces, that the conversation of the old and young ends generally with contempt or pity on either side.”
—Samuel Johnson (1709–1784)
“The Hacker Ethic: Access to computers—and anything which might teach you something about the way the world works—should be unlimited and total.
Always yield to the Hands-On Imperative!
All information should be free.
Mistrust authority—promote decentralization.
Hackers should be judged by their hacking, not bogus criteria such as degrees, age, race, or position.
You can create art and beauty on a computer.
Computers can change your life for the better.”
—Steven Levy, U.S. writer. Hackers, ch. 2, “The Hacker Ethic,” pp. 27-33, Anchor Press, Doubleday (1984)
