Automatic Creation of Thumbnails for Music Videos

摘要

There is provided a method for automatically creating a music video thumbnail ( 50 ) from a music video signal ( 12 ). The music video signal is separated into a music signal ( 16 ) and a video signal ( 18 ). The music signal is analysed by detecting similarity regions and the sections of the music signal corresponding to the chorus are extracted ( 20 ). The video signal is analysed by detecting repeated lyrics ( 34 ). The extracted chorus sections from the music signal and the sections of the video signal containing repeated lyrics are then matched. A matched pair is then selected for use in the music video thumbnail and the timing of the pair are aligned ( 42 ) to form the thumbnail.
