"This book is the Bible for anyone who needs to manage large data collections. It's required reading for our search gurus at Infoseek. The authors have done an outstanding job of incorporating and describing the most significant new research in information retrieval over the past five years into this second edition." Steve Kirsch, Cofounder, Infoseek Corporation "The new edition of Witten, Moffat, and Bell not only has newer and better text search algorithms but much material on image analysis and joint image/text processing. If you care about search engines, you need this book: it is the only one with full details of how they work. The book is both detailed and enjoyable; the authors have combined elegant writing with top-grade programming." Michael Lesk, National Science Foundation "The coverage of compression, file organizations, and indexing techniques for full text and document management systems is unsurpassed. Students, researchers, and practitioners will all benefit from reading this book." Bruce Croft, Director, Center for Intelligent Information Retrieval at the University of Massachusetts In this fully updated second edition of the highly acclaimed Managing Gigabytes, authors Witten, Moffat, and Bell continue to provide unparalleled coverage of state-of-the-art techniques for compressing and indexing data. Whatever your field, if you work with large quantities of information, this book is essential reading--an authoritative theoretical resource and a practical guide to meeting the toughest storage and access challenges. It covers the latest developments in compression and indexing and their application on the Web and in digital libraries. It also details dozens of powerful techniques supported by mg, the authors' own system for compressing, storing, and retrieving text, images, and textual images. mg's source code is freely available on the Web.

This book is a clear and comprehensive survey of multimedia system design for a networked world. It's also a perfect companion for multimedia server designers as well as the multimedia application developer ... or anyone building the 'best of breed' products and services that scale to the Internet. Dr. Eric Schmidt, Chairman and CEO Novell, Inc. This is a book on an extremely timely subject. With coming broadband access to the home, there will be an explosion in demand for multimedia streaming applications. This book will be a "must" read for anyone designing the servers that will support them. Don Towsley, Dept. of Computer Science University of Massachusetts- Amherst This book will undoubtedly satisfy the needs of application developers, server designers, integrators, and service providers, as it provides end-to-end, top-down coverage: from application-specific issues to low-level components. Inside, the authors offer specific design, development, and implementation approaches that take into account the complexity of the environments in which multimedia servers operate. You'll learn which techniques are best suited for different kinds of applications and different kinds of networks. You'll master the challenges associated with resource scheduling, collaborative computing, session set-up, and distributed storage. Most importantly, you'll discover how to put all of these solutions to work as part of a coherent strategy aimed at exploiting economies of scale and meeting quality of service requirements. Features Presents optimized design algorithms developed by the authors and other leading researchers. Deals comprehensively with the systems supporting the large-scale storage, retrieval, and distribution of audio and video data. Balances the coverage of current technologies with forward-looking discussions to help you devise a sustainable, evolvable solution. Covers key issues in video-on-demand and other multimedia systems: resource scheduling, local caching, interactivity, architectural strategies, and more.

Digital audio, video, images, and documents are flying through cyberspace to their respective owners. Unfortunately, along the way, individuals may choose to intervene and take this content for themselves. Digital watermarking and steganography technology greatly reduces the instances of this by limiting or eliminating the ability of third parties to decipher the content that he has taken. The many techiniques of digital watermarking (embedding a code) and steganography (hiding information) continue to evolve as applications that necessitate them do the same. The authors of this second edition provide an update on the framework for applying these techniques that they provided researchers and professionals in the first well-received edition. Steganography and steganalysis (the art of detecting hidden information) have been added to a robust treatment of digital watermarking, as many in each field research and deal with the other. New material includes watermarking with side information, QIM, and dirty-paper codes. The revision and inclusion of new material by these influential authors has created a must-own book for anyone in this profession. This new edition now contains essential information on steganalysis and steganography New concepts and new applications including QIM introduced Digital watermark embedding is given a complete update with new processes and applications

How to Build a Digital Library reviews knowledge and tools to construct and maintain a digital library, regardless of the size or purpose. A resource for individuals, agencies, and institutions wishing to put this powerful tool to work in their burgeoning information treasuries. The Second Edition reflects developments in the field as well as in the Greenstone Digital Library open source software. In Part I, the authors have added an entire new chapter on user groups, user support, collaborative browsing, user contributions, and so on. There is also new material on content-based queries, map-based queries, cross-media queries. There is an increased emphasis placed on multimedia by adding a "digitizing" section to each major media type. A new chapter has also been added on "internationalization," which will address Unicode standards, multi-language interfaces and collections, and issues with non-European languages (Chinese, Hindi, etc.). Part II, the software tools section, has been completely rewritten to reflect the new developments in Greenstone Digital Library Software, an internationally popular open source software tool with a comprehensive graphical facility for creating and maintaining digital libraries. Outlines the history of libraries on both traditional and digital Written for both technical and non-technical audiences and covers the entire spectrum of media, including text, images, audio, video, and related XML standards Web-enhanced with software documentation, color illustrations, full-text index, source code, and more

Digital watermarking is a key ingredient to copyright protection. It provides a solution to illegal copying of digital material and has many other useful applications such as broadcast monitoring and the recording of electronic transactions. Now, for the first time, there is a book that focuses exclusively on this exciting technology. Digital Watermarking covers the crucial research findings in the field: it explains the principles underlying digital watermarking technologies, describes the requirements that have given rise to them, and discusses the diverse ends to which these technologies are being applied. As a result, additional groundwork is laid for future developments in this field, helping the reader understand and anticipate new approaches and applications. * Emphasizes the underlying watermarking principles that are relevant for all media: images, video, and audio. * Discusses a wide variety of applications, theoretical principles, detection and embedding concepts and the key properties of digital watermarks--robustness, fidelity, data payload, and security * Examines copyright protection and many other applications, including broadcast monitoring, transaction tracking, authentication, copy control, and device control. * Presents a series of detailed examples called "Investigations" that illustrate key watermarking concepts and practices. * Includes an appendix in the book and on the web containing the source code for the examples. * Includes a comprehensive glossary of watermarking terminology
