Segmentation of Dancing Movement by Extracting Features from Motion Capture Data

抄録

Motion capture techniques have come to be used for digital archiving of intangible cultural properties especially traditional dances, and the data obtained have been used for movement analysis of these dances. The objective of this research is to develop and evaluate a method of segmenting the whole body motion data during dance into a number of unit movements. Segmentation of the body movement is an essential processing task for doing various quantitative and/or qualitative researches on dance body motion. The method uses information about velocity of body parts, a change of a movement direction, and a change of size of the space produced by the whole body. The method proposed has been evaluated by using ballet motion data and contemporary street dance data, and the experiments showed promising results.
