It will also be of interest to graduate and PhD students on media processing, coding and communications courses.

This book describes recent innovations in 3D media and technologies, with coverage of 3D media capturing, processing, encoding, and adaptation, networking aspects for 3D Media, and quality of user experience (QoE). The main contributions are based on the results of the FP7 European Projects ROMEO, which focus on new methods for the compression and delivery of 3D multi-view video and spatial audio, as well as the optimization of networking and compression jointly across the Future Internet (www.ict-romeo.eu). The delivery of 3D media to individual users remains a highly challenging problem due to the large amount of data involved, diverse network characteristics and user terminal requirements, as well as the user’s context such as their preferences and location. As the number of visual views increases, current systems will struggle to meet the demanding requirements in terms of delivery of constant video quality to both fixed and mobile users. ROMEO will design and develop hybrid-networking solutions that combine the DVB-T2 and DVB-NGH broadcast access network technologies together with a QoE aware Peer-to-Peer (P2P) distribution system that operates over wired and wireless links. Live streaming 3D media needs to be received by collaborating users at the same time or with imperceptible delay to enable them to watch together while exchanging comments as if they were all in the same location. The volume provides state-of-the-art information on 3D multi-view video, spatial audio networking protocols for 3D media, P2P 3D media streaming, and 3D Media delivery across heterogeneous wireless networks among other topics. Graduate students and professionals in electrical engineering and computer science with an interest in 3D Future Internet Media will find this volume to be essential reading.

With the rapid growth of computer and communication technologies, the creation, modification and distribution of digital multimedia information have become easier than ever. Such multimedia information includes still images, video, audio, texts and artifacts in virtual space. The efficient storage of valuable information and rapid access to it is crucial to all modern organizations.This proceedings volume consists of papers by researchers and academicians which explore the various aspects of the digital media information base. A special emphasis is placed on new database system technologies.

This book constitutes the proceedings of the International Symposium on Multimedia Communications and Video Coding (ISMCVC95) held October 11 - 13, 1995, at the Poly technic University in Brooklyn, New York. This Symposium was organized under the aus pices of the New York State funded Center for Advanced Technology in Telecommunications (CATT), in cooperation with the Communications Society and the Signal Processing Society of the Institute of Electrical and Electronic Engineers (IEEE). In preparing this book, we have summarized the topics presented in various sessions of the Symposium, including the keynote addresses, the Service Provider and Vendor Session, the Panel Discussion, as well as the twelve Technical Sessions. This summary is presented in the Introduction. 'Full papers submitted by the presenters are organized into eleven chapters, divided into three parts. Part I focuses on systems issues in multimedia communications. Part II concentrates on video coding algorithms. Part III discusses the interplay between video coding and network control for video delivery over various channels.

Signal Recovery Techniques for Image and Video Compression and Transmission establishes a bridge between the fields of signal recovery and image and video compression. Traditionally these fields have developed separately because the problems they examined were regarded as very different, and the techniques used appear unrelated. Recently, though, there is growing consent among the research community that the two fields are quite closely related. Indeed, in both fields the objective is to reconstruct the best possible signal from limited information. The field of signal recovery, which is relatively mature, has long been associated with a wealth of powerful mathematical techniques such as Bayesian estimation and the theory of projects onto convex sets (to name just two). This book illustrates for the first time in a complete volume how these techniques can be brought to bear on the very important problems of image and video compression and transmission. Signal Recovery Techniques for Image and Video Compression and Transmission, which is written by leading practitioners in both fields, is one of the first references that addresses this approach and serves as an excellent information source for both researchers and practicing engineers.

not a coincidence, but is the result of a carefully planned time of landing (sun elevation) and lander orientation (sun azimuth). * The picture was started 25 seconds after touchdown and took 15 seconds to acquire. The alternating bright and dark vertical striations at the left side of the image and the fine particles deposited on the footpad at the right side were caused by a turbulent cloud of dust raised by the lander's retrorockets. t *F.

VISUAL COMMUNICATION An Information Theory Approach Chapter 1 Introduction 1. 1 OBJECTIVE l The fundamental problem of communication, as Shannon stated it, is that of reproducing at one point either exactly or approximately a message selected at another point. In the classical model of communication (Fig. 1. 1), the infor mation source selects a desired message from a set of possible messages which the transmitter changes into the signal that is actually sent over the commu nication channel to the receiver. The receiver changes this signal back into a message, and hands this message to the destination.
