Covering some of the most cutting-edge research on the delivery and retrieval of interactive multimedia content, this volume of specially chosen contributions provides the most updated perspective on one of the hottest contemporary topics. The material represents extended versions of papers presented at the 11th International Workshop on Image Analysis for Multimedia Interactive Services, a vital international forum on this fast-moving field. Logically organized in discrete sections that approach the subject from its various angles, the content deals in turn with content analysis, motion and activity analysis, high-level descriptors and video retrieval, 3-D and multi-view, and multimedia delivery. The chapters cover the finest detail of emerging techniques such as the use of high-level audio information in improving scene segmentation and the use of subjective logic for forensic visual surveillance. On content delivery, the book examines both images and video, focusing on key subjects including an efficient pre-fetching strategy for JPEG 2000 image sequences. Further contributions look at new methodologies for simultaneous block reconstruction and provide a trellis-based algorithm for faster motion-vector decision making.

This book is a post-conference publication and contains a selection of papers presented at the VLBV workshop in 2005, which was held in Sardinia, Italy, on September 15-16. VLBV 2005 attracted very high interest among the scienti?c community, and the workshop received 85 submissions. Fifty-?ve papers were accepted and presented in three poster sessions focusing on “New Perspectives in Handling Multimedia Data”, “Wavelet Based Compression: Advances and Perspectives”, and “Applications of Distributed Video Coding”. Beyondprovidingaforumforthepresentationofhigh-qualityresearchpapers in various complementary aspects of visual content processing and distribution, the workshop gave the opportunity of exchanging ideas and opinions on hot topics in the ?elds by means of three open panels. The ?rst was devoted to the role of standards, with the attempt of both panelists and audience to provide answers to challenging questions on the success of standards, their industrial spino?, and the involvement of academic people in standardization activities. The second panel aimed to discuss the advances and the perspectives of wavelet based compression. The third one focused on the applications of distributed video coding; the discussion mainly regarded the real performance of such an approach in video coding when compared with traditional approaches. In addition to these components, the program was enriched by two sti- lating invited talks given by world-renowned researchers in the ?eld: “Digital Cinema”, by Michael W. Marcellin and “Distributed Video Coding”, by Bernd Girod.
