4. THE CASE OF THE APPLIED SYSTEM
Mpeg-7 MMDB involved in this paper provides layering technology, a wide range of functions and the methods of entry, they have a different degree of complexity, such as the development of the index, the optimization of the query, and similarity algorithm,mpeg-7 establish queries and development application. We can distinguish three levels of usage : applied use , complicated use and management, the following example is to better understand our scene .Suppose a user wants to watch a football game which provides a new target
detection applications that is based on our mpeg-7 MMDB[13] .Audio recognition of this
application ,for example the detection target is a football game screams , the similarity of research, such as a video sequence shows a restricted area and identifies the text annotation in the video sequence .In the scene of management , the user must be responsible for the maintenance of internal libraries and the system of the core management
