中文摘要 | 在本篇論文中,我們提出了一個以MPEG-7媒體內涵為基礎的分析及擷取系統。此外,為了提供多元應用的不同需求,一些特殊的特徵值也包含在這個系統當中。此系統擁有從不同的多媒體資料(如影像、聲音及圖像)中萃取多樣化特徵值的能力。由於此系統採用充分模組化的設計,因此,系統發展與特徵值萃取這兩部分的工作,可以各自獨立地發展,換句話說,當新的特徵值要加入系統中作測試時,並不會影響原本系統的設計。此外,此系統提供使用者輸入一些簡單的線索,讓使用者可以找到他們想要的多媒體資料。以此充分模組化的系統為基礎,本實驗室發展了許多相關的應用,如場景切割器,電視新聞節目分析器,商標驗證系統,魚類外形搜尋系統及家庭媒體中心 (家庭媒體資料管理系統)。 |
英文摘要 | In this paper, we proposed a content-based multimedia analysis/retrieval system basing mainly on the MPEG-7 defined features. Some new and specific features are also included for supporting various requirements of different applications. The proposed system is capable of extracting a variety of features from different kinds of media data, such as videos, audios, and images. The system design is well modularized, so that the tasks of system development and feature construction can be done independently and separately. In other words, adding a new feature into the system can be done without modifying the structure of the system. In addition, a user can also input some hints about what he or she is looking for into the system, and the system will search through the database and return the best matched candidates. On the basis of this well-modularized system, a lot of interesting applications, such as scene change detector, video news program analyzer, Logo verification system, fish shape image analysis and retrieval system, and home media center (a home media management system), have been built in the Communications and Multimedia Lab., Department of Computer Science and Information Engineering, Nation Taiwan University. |
