A content-based music retrieval system using representative melody index from music databases

Abstract

For content-based music retrieval, since not only the correctness of retrieval results but also the performance of retrievals is important, there are great needs for efficient content-based music retrieval systems that can quickly retrieve the relevant music on demand from large music database with low storage overhead. In this paper, we describe the design and implementation of a content-based music retrieval system in which the representative melody index is systemically constructed and used to support quick and appropriate retrievals to users' melody queries. By using the proposed system for digital music libraries, it could save up to 65% of index space than that for the whole motifs index while the appropriateness of retrieval results is maintained. © Springer-Verlag Berlin Heidelberg 2004.
