Research on matching method in humming retrieval

With the development of science and technology, computer technology is increasingly updated, and multimedia search technology has been widely used. For music retrieval, textbased retrieval technology can't meet the diversified retrieval needs. Humming retrieval is through matching the input audio and the audio in the database to match the audio. It's a more convenient way to retrieve music. In this paper the dynamic time wrapping matching method, hidden markov model and location sensitive hash algorithm in humming retrieval were systematically introduced, and the location sensitive hash algorithm with the dynamic time wrapping algorithm was combined to improve the retrieval rate effectively.
