| Summary: | 碩士 === 國立臺灣大學 === 資訊工程學研究所 === 90 === In this thesis, we proposed a content-based retrieval system-architecture using features defined by MPEG-7. We can use the system to extract many features from great amount of multimedia data, including video, audio and image, retrieved from daily life. An user can also input some hints about what he or she is looking for into the system, and the system will search into the database and returns the best candidates. In this system, we proposed a general structure. Under this structure, we can construct the database or search the multimedia data in the same flow for all types of multimedia data. The system is also well-modulized, so that the development of system and individual feature is independent. In addition, adding a new feature into the system can be done without modifying the current system.
In conclusion, with the amount of multimedia data grows immeasurably, and the fast development of network, how to efficiently manage and search these data becomes a very serious problem. The MPEG-7 defines and provides some tools, and we provide a system architecture using these tools.
