The availability of higher storage capacities and faster processing speeds have made it possible to store and operate on multimedia data resources such as images, graphics, 3D models, audio, speech, and video. The quantity of multimedia data available in digital archives, on the World Wide Web (WWW), and in personal and professional databases is growing rapidly. There is a need for systems that can index, store, and retrieve these media items for applications such as digital libraries, geographical information systems, video on demand services, teleconferencing, etc. However, developing these mechanisms is a difficult task due to the high volume and complexity of multimedia material, and a lack of adequate indexing standards. Since traditional database systems are inadequate in handling multimedia data, the development of multimedia databases has drawn both research and industry efforts. Although searching and querying on image databases have been studied intensively it is only in recent years, video database management systems have been researched.
