Scaling and compressing melodies using geometric similarity measures

作者:

Highlights:

• We propose efficient algorithms for two geometric problems that arise in music information retrieval; linear scaling and data compression.

• Linear scaling is used for tempo variation and melody matching, while an important application of data compression is clustering and classification.

• We use geometric matching techniques to measure the similarity between two melodies.

• Our algorithms take advantage of the properties of an optimal solution and are based on line sweeping and dynamic programming techniques.
