Maverick Shih received the B.S. degree of
Apply Math from
Fu-Jen University, Taiwan in
1995, and M.S. degree of Electrical Engineering from University of Southern
California, U.S. in 2000. He is currently a Ph.D. Candidate in the
Department of Electrical Engineering,
University of Southern California. His research
interests are in the areas of audio content analysis, multimedia database
management, preprocessing of Query by Humming system, and humming recognition.
Research Interest:
My research is focus on preprocessing part of a Query by Humming system.
Query by Humming is a system which uses human humming to do the query in music
database.
Audio content analysis and multimedia database management are two of important
preprocessing of query by humming system.
Audio content analysis:
Transferring acoustic waveform to symbolic form is a difficult task
especially for human humming. Before doing any query process, humming needs to
be converted into symbolic format for matching process. Due to the nature of
human humming, inaccurate pitch and big variation between users, humming
recognition become an interesting and challenging research topic. I tackle
this problem using statistic approach.
Multimedia database management:
Doing linear search within a huge music database is not a very good
approach, although it will return a desired result, however it usually
required a lot of time. Music database management becomes very important to
have a well-organized music database. There are features in music which can be
used to organizing music database, for example: title, artists, music type, or
repeating melodies. Repeating melodies are the keys of a music piece, and they
are easily memorized by people. Extracting repeating melodies from a piece of
music can help the management to have better organized music database.
Development tools:
HTKEdit: A GUI (Graphic User Interface) for HTK (Hidden Markov Model Toolkit), written in Visual C++
HummingDecoder: A GUI Humming Decoder using the latest note models, written in JAVA
Repeating Pattern Finder: A GUI program which finds repeating patterns in MIDI files
