The purpose of this book is to provide readers with the fundamentals of numeric databases and draw attention to them, their value, and utility to libraries and information centers. The public needs access to information which does not always appear in print format. Libraries and information centers must be aware of these resources, and recognize that they are essential information sources for a growing number of subjects. Subjects where the use of large sets of statistical data is becoming common are particularly important. This book is aimed at those readers wanting an introduction to many facets of the subject.

This book focuses particularly on content-based video retrieval. After addressing basic concepts and techniques in the field, Content-Based Video Retrieval: A Database Perspective concentrates on the semantic gap problem, i.e., the problem of inferring semantics from raw video data, as the main problem of content-based video retrieval. This book identifies and proposes the integrated use of three different techniques to bridge the semantic gap, namely, spatio-temporal formalization methods, hidden Markov models, and dynamic Bayesian networks. As the problem is approached from a database perspective, the emphasis evolves from a database management system into a video database management system. This system allows a user to retrieve the desired video sequence among voluminous amounts of video data in an efficient and semantically meaningful way. This book also presents a modeling framework and a prototype of a content-based video management system that integrates the three methods and provides efficient, flexible, and scalable content-based video retrieval. The proposed approach is validated in the domain of sport videos for which some experimental results are presented.
