Obtaining the Similarity Value of Human Body Motions Through Their Sub Motions

Abstract

This article proposes a method of measuring human body motions by using the similarity measure through a 3D chain code. The method of deriving pauses in human body motions and splitting a motion into sub motions by pauses are also introduced. The requirements of sub motions to represent the similar parts between two motions are clearly explained. The pause waveform of basic human body motions is obtained and is used to split motions into sub motions. Two options of the proposed method are evaluated by experiments. The tests for statistical significance are used in evaluating the effectiveness of the method. The result shows that the first option of the method is effective in enhancing the performing time. It is shown that the proposed method is effective in measuring the similarity of human body motions.
