Applying Voronoi Diagram in the Automatic Grouping of Polyphony

M. Hamanaka and K. Hirata

Abstract:
This paper presents a method of grouping that provides a way to automatically analyze the grouping structure of polyphony. Sets of grouping rules have been applied in previous methods, but these methods were not capable of resolving contradictions among the rules. In order to solve this problem, we propose a method where Voronoi diagrams of the notes on the piano-roll format are used to form the groups.
