Digital Halftoning [Hardcover]

Robert Ulichney (Author)

Book Description

Publication Date: June 27, 1987

Along with text and graphics, images are fast becoming a generic data type for general-purpose computer systems. This poses new problems for the systems designer, who must be able to preprocess digital image data for a wide variety of video and hard copy displays. Digital halftoning, the method by which the illusion of continuous-tone images are created through the arrangement of binary picture elements, is a key component of any preprocessing.Digital Halftoning addresses the problem of developing algorithms that best match the specific parameters of any target display device. It is the first significant study of the process of producing quality images on practical computer displays.To aid the systems designer, Ulichney devises the concept of blue noise - which has many desirable properties for halftoning - and suggests efficient algorithms for its use. He also introduces new metrics for analyzing the frequency content of periodic and aperiodic patterns for both rectangular and hexagonal grids, and presents a unique "aspect ratio immunity" argument in favor of hexagonal grids. Included are several carefully selected digitally-produced images.Robert Ulichney is Principle Engineer with the Digital Equipment Corporation.

Editorial Reviews

Review

" Digital Halftoning is a very useful compendium of techniques. It should definitely be of interest to all those people and companies involved in computer-assisted publishing and those many computer artisans involved in "desktop publishing" and related document processing techniques." Keith S. Pennington , Senior Manager, Image Technologist, IBM

"This work is unique. To the best of my knowledge no one has heretofore devoted a book solely to the digital halftone process" Paul G. Roetling , Research Fellow, Xerox

5.0 out of 5 stars Timeless Fundamentals of Halftoning, November 14, 2003

By A Customer

This review is from: Digital Halftoning (Hardcover)

It seems that everyone working in halftoning has or references this book. While there are certainly newer texts on this subject, this book continues to be the key reference for developers and researchers in the field. It is in this book that the theory and definitions of blue noise, now a central concept in halftoning, are introduced. Published in 1987, this text is certainly missing developments since then, and does not cover color issues. However, the passage of time has proven its importance as evidenced by continued and widespread reference to it; it remains an excellent resource for its presentation of foundations and fundamentals that have not changed.
