A fast query by humming system based on notes
Jingzhou Yang, Jia Liu, Weiqiang Zhang · 2010
Query by humming (QBH), a content-based retrieval method, is an efficient way to search the song from a large database. The frame-based systems can achieve a good performance, but it is time-consuming. In this paper, we proposed an efficient note-based system, which is mainly comprised of noted-based linear scaling (NLS) and noted-based recursive align (NRA). The system after post-processing can achieve 96.1 % in Top5 and 0.211s in time.
