Download or read book Absolute Identification of Color for Targets Presented Against White and Colored Backgrounds written by Harold P. Bishop and published by . This book was released on 1961 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: The number of stimulus colors which can be absolutely identified by normal subjects when viewed against various colored backgrounds was investigated. Additive mixtures of light passed through narrow-band and Illuminant-C filters were projected onto a viewing screen by a device wich permitted independent control of target and background characteristics. The stimulus parameters of hue, luminance, purity, target size, and target shape were varied, and the effects of such factors as training and the presence of a distracting task were studied. With target luminance above background luminance, about nine hues plus white, three luminance levels, and two purity levels, are estimated to be useful for operational coding, if no more than about 30 of the possible combinations are included in the set. Under optimal working conditions and with protracted training, the maximum size of an identifiable set is estimated to be about 60. Reduction of target luminance below the luminance of a colored background was found to make identification very difficult. No significant effect of target shape was found. (Author).

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 Computer Graphics written by John F. Hughes and published by Pearson Education. This book was released on 2014 with total page 1266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computer Graphics: Principles and Practice, Third Edition,remains the most authoritative introduction to the field. The first edition, the original “Foley and van Dam,” helped to define computer graphics and how it could be taught. The second edition became an even more comprehensive resource for practitioners and students alike. This third edition has been completely rewritten to provide detailed and up-to-date coverage of key concepts, algorithms, technologies, and applications. The authors explain the principles, as well as the mathematics, underlying computer graphics–knowledge that is essential for successful work both now and in the future. Early chapters show how to create 2D and 3D pictures right away, supporting experimentation. Later chapters, covering a broad range of topics, demonstrate more sophisticated approaches. Sections on current computer graphics practice show how to apply given principles in common situations, such as how to approximate an ideal solution on available hardware, or how to represent a data structure more efficiently. Topics are reinforced by exercises, programming problems, and hands-on projects. This revised edition features New coverage of the rendering equation, GPU architecture considerations, and importance- sampling in physically based rendering An emphasis on modern approaches, as in a new chapter on probability theory for use in Monte-Carlo rendering Implementations of GPU shaders, software rendering, and graphics-intensive 3D interfaces 3D real-time graphics platforms–their design goals and trade-offs–including new mobile and browser platforms Programming and debugging approaches unique to graphics development The text and hundreds of figures are presented in full color throughout the book. Programs are written in C++, C#, WPF, or pseudocode–whichever language is most effective for a given example. Source code and figures from the book, testbed programs, and additional content will be available from the authors' website (cgpp.net) or the publisher's website (informit.com/title/9780321399526). Instructor resources will be available from the publisher. The wealth of information in this book makes it the essential resource for anyone working in or studying any aspect of computer graphics.
