Abstract

Storage and retrieval of multimedia has become a requirement for many contemporary information systems. These systems need to provide browsing, querying, navigation and sometimes composition capabilities involving various forms of media. In this survey we review techniques and systems for image and video retrieval. We first look at visual and non-visual features for image retrieval and techniques for using them. Temporal aspects of video retrieval are discussed next. We review several research and commercial systems including WWW-based systems and conclude with future directions. 1 Introduction The increasing availability of multimedia information combined with the decreasing storage and processing costs have changed the requirements on information systems drastically. Today, general purpose database systems are incorporating support for multimedia storage and retrieval, as well as features which used to be found in specialized imaging systems or multimedia databases. Increased use of...
