Skill Level Evaluation for Taijiquan Based on Curve Fitting and Logarithmic Distribution Diagram of Curvature

摘要

This paper proposes an objective skill level evaluation method for Taijiquan. The proposed skill level evaluation method utilizes both curve fitting to spiral motion and classification based on a logarithmic distribution diagram of curvature for a human body part. In order to demonstrate a possibility of the proposed method, the paper presents experimental results with a Kinect sensor for three subjects, i.e., a beginner, intermediate and expert.
