The decreasing costs of consumer electronic devices such as digital cameras and digital camcorders, along with the ease of transportation facilitated by the Internet, has lead to a phenomenal rise in the amount of multimedia data generated and distributed. Given that this trend of increased use of multimedia data is likely to accelerate, there is an urgent need for providing a clear means of capturing, storing, indexing, retrieving, analyzing and summarizing such data. Content-based access to multimedia data is of primary importance since it is the natural way by which human beings interact with such information. To facilitate the content-based access of multimedia information, the first step is to derive feature measures from these data so that a feature space representation of the data content can be formed. This can subsequently allow for mapping the feature space to the symbol space (semantics) either automatically or through human intervention. Thus, signal to symbol mapping, useful for any practical system, can be successfully achieved. Perspectives on Content-Based Multimedia Systems provides a comprehensive set of techniques to tackle these important issues. This book offers detailed solutions to a wide range of practical problems in building real systems by providing specifics of three systems built by the authors. While providing a systems focus, it also equips the reader with a keen understanding of the fundamental issues, including a formalism for content-based multimedia database systems, multimedia feature extraction, object-based techniques, signature-based techniques and fuzzy retrieval techniques. The performance evaluation issues of practical systems is also explained. This book brings together essential elements of building a content-based multimedia database system in a way that makes them accessible to practitioners in computer science and electrical engineering. It can also serve as a textbook for graduate-level courses.

Download or read book Content-Based Video Retrieval written by Milan Petković and published by Springer Science & Business Media. This book was released on 2003-10-31 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: The area of content-based video retrieval is a very hot area both for research and for commercial applications. In order to design effective video databases for applications such as digital libraries, video production, and a variety of Internet applications, there is a great need to develop effective techniques for content-based video retrieval. One of the main issues in this area of research is how to bridge the semantic gap between low-Ievel features extracted from a video (such as color, texture, shape, motion, and others) and semantics that describe video concept on a higher level. In this book, Dr. Milan Petkovi6 and Prof. Dr. Willem Jonker have addressed this issue by developing and describing several innovative techniques to bridge the semantic gap. The main contribution of their research, which is the core of the book, is the development of three techniques for bridging the semantic gap: (1) a technique that uses the spatio-temporal extension of the Cobra framework, (2) a technique based on hidden Markov models, and (3) a technique based on Bayesian belief networks. To evaluate performance of these techniques, the authors have conducted a number of experiments using real video data. The book also discusses domains solutions versus general solution of the problem. Petkovi6 and Jonker proposed a solution that allows a system to be applied in multiple domains with minimal adjustments. They also designed and described a prototype video database management system, which is based on techniques they proposed in the book.

Download or read book Multimedia Database in Perspective written by Peter M.G. Apers and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last decade, multimedia has emerged as a major research and de velopment area. Pushed by advanced technology like huge-capacity storage de vices, fast networks, and powerful work stations, new applications have arisen. Many definitions of multimedia systems exist, one of them being computer sys tems that support interactive use of at least one of the following information sources: graphics, image, voice, sound, and video. These systems have caused a boom in the world of entertainment, but also in other business areas great opportunities for novel products and services are available. The size of multi media data is often huge, and the storage of huge amounts of data is a task normally allocated to database management systems. Although some modern database management systems offer facilities to support development of multi media applications, many problems related to multimedia support are still not well understood. This book reports on research efforts to solve some of these problems. An in troductory knowledge of databases, and also of operating systems and network technology is assumed. The book is very suitable as material for courses at senior or graduate level, but also for upgrading the skills of computer scientists working on database management systems, multimedia systems or applications. The book consists of four parts. Part I is called "Requirements for a Mul timedia Database" and comprises chapters one to three. Chapter one presents an outline of the book.

Download or read book Semantic Video Object Segmentation for Content-Based Multimedia Applications written by Ju Guo and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Semantic Video Object Segmentation for Content-Based Multimedia Applications provides a thorough review of state-of-the-art techniques as well as describing several novel ideas and algorithms for semantic object extraction from image sequences. Semantic object extraction is an essential element in content-based multimedia services, such as the newly developed MPEG4 and MPEG7 standards. An interactive system called SIVOG (Smart Interactive Video Object Generation) is presented, which converts user's semantic input into a form that can be conveniently integrated with low-level video processing. Thus, high-level semantic information and low-level video features are integrated seamlessly into a smart segmentation system. A region and temporal adaptive algorithm was further proposed to improve the efficiency of the SIVOG system so that it is feasible to achieve nearly real-time video object segmentation with robust and accurate performances. Also included is an examination of the shape coding problem and the object segmentation problem simultaneously. Semantic Video Object Segmentation for Content-Based Multimedia Applications will be of great interest to research scientists and graduate-level students working in the area of content-based multimedia representation and applications and its related fields.

Download or read book Central and Eastern European Media in Comparative Perspective written by John Downey and published by Routledge. This book was released on 2016-04-15 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Appearing more than twenty years after the revolutions in Central and Eastern Europe, this book could not have come at a more appropriate time; a time to take stock not only of the changes but also the continuities in media systems of the region since 1989. To what extent are media institutions still controlled by political forces? To what extent are media markets operating in Central and Eastern Europe? Do media systems in Central and Eastern Europe resemble media systems in other parts of Europe? The answers to these questions are not the same for each country in the region. Their experience is not homogeneous. An international line up of distinguished experts and emerging scholars methodically examine the different economic, political, cultural, and transnational factors affecting developments in media systems across Central and Eastern Europe. Whereas earlier works in the media system tradition have, in the main, adopted the political framework of comparative politics, the authors argue that media systems are also cultural and economic institutions and there are other critical variables that might explain certain outcomes better. Topics discussed range from political economy to gender inequality to the study of ethno-cultural diversity. This unmatched volume gives you the unique opportunity to study the growing field of comparative media analysis across Eastern and Western Europe. A valuable resource that goes beyond the field of media and cultural analysis which media scholars as well as to area specialists should not go without!
