摘要

We synchronize background music with a video by changing the timing of music, an approach that minimizes the damage to music data. Starting from a MIDI file and video data, feature points are extracted from both sources, paired, and then synchronized using dynamic programming to time-scale the music. We also introduce the music graph, a directed graph that encapsulates connections between many short music sequences. By traversing a music graph, we can generate large amounts of new background music, in which we expect to find a sequence which matches the video features better than the original music.
