Motion AnalysisWe propose a new framework for dance motion analysis and editing using HHT, and attempt to extract new features from a famous Japanese pop threesome singer group "Perfume" dance, Salsa dance etc. We find some characteristic “choreographic” primitives using our method in the Hilbert spectrum. The proposed framework can reveal the detailed “choreographic” primitives synchronized to the dance beats. Thus, the framework can lead us to understand the dance motion in detail. Perfume Dance Motion Analysis Motion EditingFor dance synthesis, we decompose their dance motions into different modes (IMFs), and scale, combine, subtract, exchange, and modify different modes (IMFs) of different dances to create new dance motions self-consistently. The HHT and our framework can be considered to be a very powerful and useful tool to decompose, blend, and edit dance motions for animators.
