Dieses Standardlehrbuch der Signalübertragung liegt nunmehr in der 12. Auflage vor. Das didaktisch hervorragend konzipierte und bewährte Lehrbuch vermittelt eine Einführung in die Grundlagen der Signal- und Systemtheorie einschließlich stochastischer Methoden (Teil A), sowie der Prinzipien der Informationsübertragung (Teil B).

Neu in der 12. Auflage sind eine Reihe von Aktualisierungen und Ergänzungen in Teil B. Sie ermöglichen ein noch detaillierteres Verständnis der Übertragungsverfahren aktueller Systeme der Kommunikationstechnik wie z.B. LTE. Insbesondere die Abschnitte zu OFDM und MIMO wurden in diesem Sinne überarbeitet.

Aufgaben zu weiterführenden Problemen einschließlich ausführlicher Lösungen runden das Buch ab. Die Lösungen zu den übrigen Übungsaufgaben sind im Internet verfügbar.

This textbook covers thetheoretical background of one- and multidimensional signal processing,statistical analysis and modelling, coding and information theory with regardto the principles and design of image, video and audio compression systems. Thetheoretical concepts are augmented by practical examples of algorithms formultimedia signal coding technology, and related transmission aspects. On thisbasis, principles behind multimedia coding standards, including most recentdevelopments like High Efficiency Video Coding, can be well understood.Furthermore, potential advances in future development are pointed out. Numerousfigures and examples help to illustrate the concepts covered. The book wasdeveloped on the basis of a graduate-level university course, and most chaptersare supplemented by exercises. The book is also a self-contained introductionboth for researchers and developers of multimedia compression systems inindustry.

This textbook covers the theoretical backgrounds and practical aspects of image, video and audio feature expression, e.g., color, texture, edge, shape, salient point and area, motion, 3D structure, audio/sound in time, frequency and cepstral domains, structure and melody. Up-to-date algorithms for estimation, search, classification and compact expression of feature data are described in detail. Concepts of signal decomposition (such as segmentation, source tracking and separation), as well as composition, mixing, effects, and rendering, are discussed. Numerous figures and examples help to illustrate the aspects covered. The book was developed on the basis of a graduate-level university course, and most chapters are supplemented by problem-solving exercises. The book is also a self-contained introduction both for researchers and developers of multimedia content analysis systems in industry.
