| Abstract: | Traditional simple method of retrieval is no longer adequate for multimedia data,since the digitized representation of images,video,or data do not convey the reality of these mediaitems.The research of content-based musical retrieval is composed of the study of musical theoretics,signal processing and pattern recognition.And it is significant for the management of the music digital library,the music search in the Internet and the daily amusement.Therefore,content-based retrieval for audio data is realized taking such intrinsic features of multimedia data into account.Surveys recent studies on content-based retrieval for music databases from the point of view of some fundamental issues. |
