Humming-based Music Retrieval System Research And Design

Image retrieval, Video retrieval and Audio retrieval are the hot topics in the retrieval research fields. But the emphasis of the multimedia information retrieval fields is mainly focusing on image and video retrival, there are less returns on the music retrieval fields. With music repidly rising and people's lover on music, thenology of music retrieval is widely applied in the places of voice dialing, KA OK, KTV concert hall, music library retrieval system. How to retry music information is mainly the purpose of this thesis, the user only need to hum part of a song, thence, can get the song he or she wanted.Based on the technology of the query by humming, the main works in this paper are as follows:1)Making a comprehensive overview of the paper. Describes content-based music retrieval research purposes, significance and present status, then, pointed advantages and complexity of the content-based music retrieval.2)Describes basic knowledge of the content-based music retrieval. Through the study of music digital, gives the music signal characteristics and it`s extraction methods.3)Giving system framework of the content-based music retrieval. By analyzing the principle of content-based music retrieval, given research programs and process framework of the humming music retrieval.4)Analysis of the traditional matching methods, a modified dynamic time warping (DTW) similarity matching algorithm are propose by us. The results show that reducing the number of songs which the library of songs exactly (DTW) match, shortening the retrieval time to increase the retrieval speed5)Finally, a content-based music humming retrieval system are designed and implemented . After a large number of experiments, the system without prior training in the subject, still has a higher accuracy.A query by humming retrieval system of this thesis has a good recognizable effect. The study work of this thesis provides the preparation for the development of content-base query by humming retrieval research and provided method and experience in the further study of music retrieval.
