Digital Image Processing: Concepts, Algorithms, and Scientific Applications
by Bernd JähneIntended as a practical guide, the book takes the reader from basic concepts to up-to-date research topics in digital image processing. Only little special knowledge in computer sciences is required since many principles and mathematical tools widely used in natural sciences are also applied in digital image processing thus the reader with a general background in natural science gets an easy access to the material presented. The book discusses the following topics: image acquisition and digitization; linear and nonlinear filter operations; edge detection; local orientation and texture; fast algorithms on pyramidal and multigrid data structures; morphological operations to detect the shape of objects; segmentation and classification. Further chapters deal with the reconstruction of three-dimensional objects from projections and the analysis of stereo images and image sequences with differential, correlation, and filter algorithms. Many examples from different areas show how the reader can use digital image processing as an experimental tool for image data acquisition and evaluation in his or her research area.
Digitale Bildverarbeitung
by Bernd JähneDiese praxisorientierte Einführung baut auf Prinzipien und mathematischen Methoden auf, die aus Naturwissenschaft und Technik bekannt sind. Es werden keine speziellen Kenntnisse der Informatik vorausgesetzt. Das Buch führt von den Grundlagen zu den aktuellen Konzepten der Bildverarbeitung. Es behandelt: Bildaufnahme; Bildverbesserung; Lineare und nichtlineare Filteroperationen zur Erkennung von Kanten, lokaler Orientierung und Textur; Pyramiden; Segmentierung und Klassifizierung. Weitere Kapitel befassen sich mit der Rekonstruktion dreidimensionaler Bilder aus Projektionen und mit Gradienten-, Korrelations- und Filterverfahren zur Analyse von Bewegungen in Bildfolgen. Praktische Beispiele aus zahlreichen Fachgebieten illustrieren - zum Teil in Farbe - die Darstellung. Sie zeigen dem Leser, daß selbst komplexe Aufgaben mit kostengünstigen Bildverarbeitungssystemen auf der Basis eines Personalcomputers durchführbar sind. Die zweite Auflage wurde vollständig neu bearbeitet und aktualisiert. Insbesondere neueste Entwicklungen der PC-Hardware wurden berücksichtigt. Das Buch wendet sich an Studenten, Wissenschaftler und Ingenieure, die sich mit digitaler Bildverarbeitung und ihrer praktischen Anwendungsmöglichkeit in Wissenschaft und Technik vertraut machen wollen.
Digitale Kommunikationsnetze: Prinzipien, Einrichtungen, Systeme
by Peter R. GerkeIn der Telekommunikationstechnik hat Anfang der 80er Jahre eine neue Epoche begonnen, deren Ende noch nicht abzusehen ist. Nach dem Übergang von der Elektromechanik über rechnergesteuerte Vermittlungssysteme zur Digitalübermittlung ist man nun dabei, auf der Hardwareseite die Breitbandkommunikation, auf der Softwareseite diensteintegrierende und intelligente Netze zu realisieren. Diese beiden Aufgaben werden im vorliegenden Buch behandelt. Wie in seinen Vorgängerwerken erklärt der Autor auch diesmal wieder Stand und künftige Entwicklung dieses wichtigen Gebietes der Nachrichtentechnik in einer auch Nichtspezialisten ansprechenden Form. Die thematische Vielfalt und die Allgemeinverständlichkeit der Darstellung erleichtern sowohl Ingenieuren die Einarbeitung in die komplexen technischen Zusammenhänge als auch Verantwortlichen aus Verwaltung und Wirtschaft die Vorbereitung auf meist sehr weitgehende Entscheidungen über betriebliche, regionale, nationale und internationale Netze. Daneben erschließt das Buch Studenten der Nachrichtentechnik Gegenwart und Zukunft des Telekommunikationswesens.
Digitale Signalverarbeitung: Grundlagen, Theorie, Anwendungen in der Automatisierungstechnik (Hochschultext)
by Heinz KronmüllerDie digitale Verarbeitung analoger Signale, und dies oft in hohen Raten, stellt eine zentrale Aufgabe sowohl experimentell arbeitender Naturwissenschaftler als auch der Ingenieure in Automatisierung oder im Versuchsfeld dar. Das Lehrbuch geht von den mathematischen Grundbegriffen der Funktionsanalysis aus und baut die digitale Signalverarbeitung als Zweig der Systemtheorie und Mathematik auf. Der Autor liefert eine systematische, geschlossene Darstellung, die nicht nur Teilaspekte behandelt. Eine große Zahl von Beispielen aus der Automatisierungstechnik stellen den unmittelbaren Praxisbezug her und liefern die Ansätze für Problemlösungen. Angesprochen werden daher nicht nur Studenten der Elektro- und Automatisierungstechnik, sondern auch Ingenieure in der industriellen Praxis, wie auch Naturwissenschaftler, die mit der Verarbeitung analoger Signale zu tun haben.

by William Nagler Anne AndroffEveryone wants to have a nurturing, happy, working union with a spouse or loved one--but time after time, it can fail, fall flat, or not live up to expectations. Now, after surveying more than 30 years of psychiatric literature and submitting more than 1,000 relationship studies to computer analysis, a renowned psychiatrist offers a provocative new theory for successful, long-lasting love.
Document Architecture in Open Systems: The ODA Standard
by Wolfgang AppeltIn 1989, the ISO Standard 8613 "Office Document Architecture (ODA) and Interchange Format" was published. The Standard is intended for the interchange of documents in an Open Systems environment. ISO 8613 is technically identical to the CCITT Recommendations of the T.410 series called "Open Document Architecture (ODA) and Interchange Format" published in 1988. Almost all major companies in the office automation and telecommunication area are currently developing products based on this Standard. In this book, all important aspects of the presently publishedeight parts of the Standard are discussed. The book provides a comprehensiveand detailed introduction to the technical specifications of ISO 8613 and the concepts on which these specifications are based, including the extensions which were added to the ODA Standard in 1991. The book isprimarily addressed to readers who want to investigate the applicability of the Standard for their document interchange problems, plan to acquire products based on the Standard, or intend to develop document processingsystems conforming to the Standard.

Empire of the Air: The Men Who Made Radio
by Tom LewisEmpire of the Air tells the story of three American visionaries—Lee de Forest, Edwin Howard Armstrong, and David Sarnoff—whose imagination and dreams turned a hobbyist's toy into radio, launching the modern communications age. Tom Lewis weaves the story of these men and their achievements into a richly detailed and moving narrative that spans the first half of the twentieth century, a time when the American romance with science and technology was at its peak. Empire of the Air is a tale of pioneers on the frontier of a new technology, of American entrepreneurial spirit, and of the tragic collision between inventor and corporation.
The Executive's Handbook of Trade and Business Associations: How They Work--And How to Make Them Work Effectively for You
by Charles S. MackThis handbook is a comprehensive guide to the different types of business associations: multi-industry umbrella organizations, single-industry trade associations, professional societies, and chambers of commerce. It is written for senior corporate executives and public affairs officers who want to evaluate the effectiveness of trade and business associations to which their companies belong and to optimize the benefits of participation to achieve corporate objectives, especially in the fields of government relations and economic services. It is also intended for association executives concerned about corporate dues cutbacks who want to help their memberships increase the value of association memberships and to better understand the world of associations. Mack maintains that few firms undertake tost-benefit analyses of their association memberships or take the steps necessary to assure that these organizations meet the company's unique special needs as well as the common interests of the membership at large. He therefore focuses particular attention on techniques designed to help members evaluate and intensify their effectiveness and influence within each of their associations while strengthening the association at the same time. He also examines the environment of association operations: association resources and regulation, the inner workings of association management, and future changes.The book begins with a description of associations as interest groups and their growing importance in the formation of public policy. The author describes non-business interest groups, the types and characteristics of business associations, and the historic development of business organizations in Europe, Japan, and the U.S. In Part II, Mack focuses on techniques to evaluate associations and introduces the Effective Membership Process by which individual members can enhance their influence. The third section explains association resources including membership; finance, planning, and budgeting; governance and policymaking; regulation and taxation of associations; and the roles of the staff. Part IV analyzes the nature of national, international, and state and local associations, comparing their similarities and differences. Illustrative profiles of eight widely varying associations are included in this section. Finally, the book offers an analysis of the attitudes of corporate and individual members towards their associations. Based on the conclusions drawn from this analysis, the author sets down a concrete set of recommendations for strengthening the effectiveness of these organizations to meet the new challenges of the rapidly changing business environment and global economy. A detailed appendix describing how to start a new association completes the handbook.

Fotorealistische Computeranimation
by Wolfgang Leister Heinrich Müller Achim StößerDie heutige Computergraphik in ihren vielfältigen Anwendungen zeigt eine Tendenz zu Farbe und Bewegung. Die immer häufiger als Vorspann, in Werbespots, aber auch in wissenschaftlichen Visualisierungen verwendeten rechnergenerierten Animationen erzielen ihre Wirkung durch die Simulation optischer Effekte, etwa des Reflexionsverhaltens metallischer Oberflächen, und durch ausgefeilte Bewegungsabläufe bis hin zu korrektem physikalischen Verhalten. In diesem Buch werden Techniken zur Produktion derartiger fotorealistischer Computeranimationen vorgestellt und anhand des Computerfilms Occursus cum Novo demonstriert. Die Kapitel werden durch Übersichten zum Stand der Technik und Verweise auf relevante weiterführende Literatur abgeschlossen. Für potentielle Entwickler von Animationssystemen werden in diesem Buch grundlegende Verfahren und ihre effiziente Umsetzung in Algorithmen und Software dargestellt. Anwender erfahren technische Einzelheiten, die helfen können, die Wirkungsweise der eingesetzten Systeme besser zu verstehen. Das umfangreiche, überwiegend farbige Bildmaterial vermittelt auch dem nicht technisch orientierten Leser den "Stand der Kunst".
Fund Raising and Public Relations: A Critical Analysis (Routledge Communication Ser.)
by Kathleen S. KellyThis is the first scholarly work to place the function of fund raising within the field of public relations, redefining it as a specialization responsible for the management of communication between a charitable organization and its donor publics. Combining her academic interest in communication with her experience as a fund raiser, the author has produced one of the few critical studies on fund raising, challenging current perspectives and employing systems theory and the concept of organizational autonomy to lead to a new and different approach. Until now, fund raising has been an anomaly, without an academic home and with few general theories to guide practitioner behavior. This book theoretically grounds fund raising and develops a theory that provides a fuller understanding of one of the fastest growing occupations in the nonprofit sector.

Fundamentals of Electronic Imaging Systems: Some Aspects of Image Processing (Springer Series in Information Sciences #15)
by William F. SchreiberImage processing is a fascinating applications area, not a fundamental science of sufficient generality to warrant studying it for its own sake. In this area, there are many opportunities to apply art and experience, as well as knowledge from a number of sciences and engineering disciplines, to the creation of products and processes for which society has an expressed need. Without this need, work in the field would be sterile, but with it, image processing can readily provide the interested scientist or engineer with a professional lifetime of challenging problems and corresponding rewards. This point of view motivates this book and has influenced the selection and treatment of topics. I have not attempted to 1 be encyclopedic; this service has already been performed by others. It will be noted that the word "digital" is not in the title of this book. While much of present-day image processing is implemented digitally, this work is not intended for those who think of image processing as a branch of digital signal processing, except, perhaps, to try to change their minds. Image gathering and image display, vital parts of the field with strong effects on image quality, are inherently analog, as is image transmission in today's most important medium, the over-the-air broadcasting channel. The latter is not about to die, as it is by far the cheapest way to deliver broadband signals to the home. Likewise, the principal means of recording images on paper are continuous and not discrete.
Gay People, Sex, and the Media
by Michelle Wolf Alfred KielwasserHere is a provocative book that examines precisely how and why mass communication has an impact upon the sexual realities of our lives. Written in response to a demand for information that cuts across many of the boundaries found in more traditional books on sexuality and mass communication, Gay People, Sex, and the Media covers a broad range of sexual identity, socialization, and mass communication issues and represents a variety of theoretical and methodological orientations. Although the chapters are diverse, they all focus on how the mass media--television, radio, films, newspapers, magazines, and recorded music--contribute significantly to the very definitions we form of ourselves and of each other. In part, this informative volume discusses and analyzes several concerns regarding minority perspectives in the context of the the study of mass media content and effects; analyzes mediated information about AIDS and highlights the responsibility of the mass media to disseminate more accurate information; addresses the relationships between mass media content (primarily television) and sexual socialization; explores issues confronted by individuals whose sexual orientations are generally perceived as falling out of the mainstream; and provides a selective bibliography of print, aural, and visual resources on gay men, lesbians, and the mass media. Unique in contrast to other books of research on human sexuality and mass communication, Gay People, Sex, and the Media gives more than a passing reference to issues concerning sexual identity and gay and lesbian concerns. Scholars and students of human sexuality, especially those who wish to explore their field from a communications perspective, will find this to be a valuable book. It is also useful to communications researchers and teachers, particularly those studying mediated communications in society, media ethics, and sex and the media. Finally, for professionals involved in creating or monitoring media content or forging public policy and community action programs in response to these issues, this volume serves as an essential sourcebook.

Glasfaser bis ins Haus / Fiber to the Home: Vorträge des am 14./15. November 1990 in München abgehaltenen Kongresses / Proceedings of a Congress Held in Munich, November 14/15, 1990 (Telecommunications #16)
by Wolfgang KaiserSysteme zur optischen Übertragung in Glasfaserkabeln sind im Nachrichten-Weitverkehr bereits heute wirtschaftlicher als entsprechende Kupferkabelsysteme. Hier kommen die beiden großen Vorteile der optischen Übertragung in Glasfasern, nämlich die geringe Dämpfung und die große Bandbreite, voll zum Tragen. Die Möglichkeit einer Breitbandkommunikation mit Integration der verschiedensten Dienste auf der Basis von Glasfaser-Teilnehmeranschlußleitungen wird seit einer Reihe von Jahren intensiv untersucht. Darüber hinaus werden weltweit große Anstrengungen unternommen, durch Fortschritte in den optischen Komponenten, der Kabel- und Verbindungstechnik und insbesondere durch den Einsatz der Mikroelektronik und integrierten Optik Teilnehmeranschlüsse in Glasfasertechnik auch für Schmalbanddienste, also z.B. für Fernsprechen, genauso wirtschaftlich zu machen wie die herkömmlichen Anschlüsse in Kupfertechnik. Ziel des Kongresse war es, die im In- und Ausland beschrittenen Wege zu wirtschaftlichen Teilnehmeranschlüssen in Glasfasertechnik aufzuzeigen und damit einen Beitrag zur baldigen Einführung dieser zukunftsorientierten Technik zu leisten.
High-Capacity Local and Metropolitan Area Networks: Architecture and Performance Issues (NATO ASI Subseries F: #72)
by Guy PujolleThe main objective of this workshop was to review and discuss the state of the art and the latest advances· in the area of 1-10 Gbit/s throughput for local and metropolitan area networks. The first generation of local area networks had throughputs in the range 1-20 Mbit/s. Well-known examples of this first generation networks are the Ethernet and the Token Ring. The second generation of networks allowed throughputs in the range 100-200 Mbit/s. Representatives of this generation are the FDDI double ring and the DQDB (IEEE 802.6) networks. The third generation networks will have throughputs in the range 1-10 Gbit/s. The rapid development and deployment of fiber optics worldwide, as well as the projected emergence of a market for broadband services, have given rise to the development of broadband ISDN standards. Currently, the Asynchronous Transfer Mode (ATM) appears to be a viable solution to broadband networks. The possibility of all-optical networks in the future is being examined. This would allow the tapping of approximately 50 terahertz or so available in the lightwave range of the frequency spectrum. It is envisaged that using such a high-speed network it will be feasible to distribute high-quality video to the home, to carry out rapid retrieval of radiological and other scientific images, and to enable multi-media conferencing between various parties.

Kalman Filtering: with Real-Time Applications (Springer Series in Information Sciences #17)
by Charles K. Chui Guanrong ChenIn addition to making a number of minor corrections and updat ing the references, we have expanded the section on "real-time system identification" in Chapter 10 of the first edition into two sections and combined it with Chapter 8. In its place, a very brief introduction to wavelet analysis is included in Chapter 10. Although the pyramid algorithms for wavelet decompositions and reconstructions are quite different from the Kalman filtering al gorithms, they can also be applied to time-domain filtering, and it is hoped that splines and wavelets can be incorporated with Kalman filtering in the near future. College Station and Houston Charles K. Chui September 1990 Guanrong Chen Preface to the First Edition Kalman filtering is an optimal state estimation process applied to a dynamic system that involves random perturbations. More precisely, the Kalman filter gives a linear, unbiased, and min imum error variance recursive algorithm to optimally estimate the unknown state of a dynamic system from noisy data taken at discrete real-time. It has been widely used in many areas of industrial and government applications such as video and laser tracking systems, satellite navigation, ballistic missile trajectory estimation, radar, and fire control. With the recent development of high-speed computers, the Kalman filter has become more use ful even for very complicated real-time applications.
Language In The News: Discourse And Ideology In The Press (PDF)
by Roger FowlerNewspaper coverage of world events is presented as the unbiased recording of hard facts. In this study of both the quality and the popular press, Roger Fowler challenges this perception, arguing that news is a practice, a product of the social and political world on which it reports. Writing from the perspective of critical linguistics, Fowler examines the crucial role of language in mediating reality. Starting with a general account of news values and the processes of selection and transformation which go to make up the news, Fowler goes on to consider newspaper representations of gender, power, authority and law and order. He discusses stereotyping, terms of abuse and endearment, the editorial voice and the formation of consensus. Fowler's analysis takes in some of the major news stories of the Thatcher decade - the American bombing of Libya in 1986, the salmonella-in-eggs affair, the problems of the National Health Service and the controversy of youth and contraception.
