Visual Rhythm Detection and Its Applications in Interactive Multimedia
Although music is typically considered a strictly auditory art form, human interaction with music consists of a much richer combination of auditory, visual, and physical experiences and responses. From traditional folk dance to classical ballet, or from the latest music videos to just getting down on the dance floor, physical movement and other visual stimuli have always been closely tied to the musical art form. The link between all of this is rhythm. Rhythm has been extensively studied in the fields of audio signal processing and music information retrieval and many systems now can automatically extract the rhythm and tempo from an audio signal.
