Grace feature extraction focusing on the curved surface created by arm trajectories in classical dance

Abstract

The purpose of this study is to propose the quantification method of grace from the classical dance motion. William Hogarth said that human motion trajectory which includes ”the line of beauty” seems graceful. We proposed a new method to extract ”the line of beauty” features from the curved surface formed by arm movements and to quantify the grace features. In this report describes the performance verification of the proposed quantification method.
