Springer, 2004. — 859 p.Information technology provides a plenty of new ways to process, store, distribute and access audiovisual information. Beyond traditional broadcast and telephone channels and analog storage media like film or tapes, the emerging Internet, mobile networks and digital storage are going to revolutionize the terms of distribution and access. This development is ruled by the convergence of audiovisual media technology, information technology and telecommunications technology. By capabilities of digital processing, established media like photography, movie, television and radio are changing their roles and are becoming subsumed by new integrated services which are mobile, interactive, pervasive, usable from anywhere, giving freedom to play with, and penetrating everyday life. Multimedia communication establishes new forms of communication between people, between people and machines, allows also communication between machines using audiovisual information or related feature parameters. Intelligent media interfaces are becoming increasingly important, and machine assistance in accessing media, in acquiring, organizing, distributing, manipulating and consuming audiovisual information becomes inevitable in the future. This book intends to provide a deep insight into important enabling technologies of multimedia communication systems, which are methods of multimedia signal processing, analysis, identification and recognition, and schemes for multimedia signal representation, compression and expression by features or other properties. All these are lively and highly innovative areas at present, where this book reviews state-of-the-art technology and its scientific foundations, but shall primarily support systematic understanding of underlying methods, algorithms and their theoretical foundations . It is strongly believed that this is the best approach to contribute to future improvements in the field. In part, the book is a substantially upgraded translation ofmy German language textbook on digital image and video coding, which was published by the mid '90s. Since then, the progress that was made in compression of audiovisual data has been breath-taking, and consequently newest developments are reflected, including the Advanced Video Coding standard and motion-compensated Wavelet coding. The second basis for this book are my lectures on topics of multimedia communications held regularly at RWTH Aachen University. These treat all aspects of image, video and audio compression, including networking interfaces, and also include multimedia signal identification and recognition . These latter aspects, topically related to the MPEG-7 multimedia content description standard, establish a profound basis for intelligent multimedia systems.Introduction Part A: Multimedia Signal Processing and Analysis Signals and Sampling Statistical Analysis of Multimedia Signals Linear Systems and Transforms Pre- and Postprocessing Part B: Content-related Multimedia Signal Analysis Perceptual Properties of Vision and Hearing Features of Multimedia Signals Signal and Parameter Estimation Feature Transforms and Classification Signal Decomposition Part C: Coding of Multimedia Signals Quantization and Coding Still Image Coding Video Coding Audio Coding Part D: Applications and Standards Transmission and Storage Signal Composition, Rendering and Presentation Multimedia Representation Standards
