Abstract
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.
Claims15
A method for automatically creating a music video thumbnail of a music video signal, comprising the steps of:
- separating the music video signal into a music signal and video signal;
- extracting the sections of the music signal corresponding to the chorus by detecting similarity regions;
- determining repeated lyrics in the video signal;
- matching repeated lyrics with the corresponding chorus section;
- selecting a repeated lyrics and chorus pair;
- and
- aligning and combining said selected pair to create said music video thumbnail.
A system for automatically creating a music video thumbnail of a music video signal, comprising:
- means for separating the music video signal into a music signal and video signal;
- means for extracting the sections of said music signal corresponding to the chorus by detecting similarity regions;
- means for determining repeated lyrics in said video signal;
- means for matching said repeated lyrics with a corresponding one of said chorus sections';
- means for selecting a repeated lyric and chorus pair;
- and
- means for aligning and combining said selected pair to produce said music video thumbnail.
A computer program product embodied on a computer readable medium and comprising code that, when executed, causes a computer to perform a method for automatically creating a music video thumbnail of a music video signal, said method comprising the steps of:
- separating the music video signal into a music signal and video signal;
- extracting the sections of the music signal corresponding to the chorus by detecting similarity regions;
- determining repeated lyrics in the video signal;
- matching repeated lyrics with the corresponding chorus section;
- selecting a repeated lyrics and chorus pair;
- and
