The behavior analysis in intelligent control, human-computer interaction, video conferencing has a wide range of applications, it has become one of the most attractive areas in computer vision. The main purpose is to extract movement information from the video, and then conduct the analysis and identification. This paper is based on behavior analysis of the status quo, applies the idea of parameter to behavior analysis. According to human skeleton extracted from the video sequence, we can determine the limb endpoints and joint points, and establish a parametric equation to describe human behavior state. Tracking one key point in different frames and recording coordinates, we can establish a cubic spline function to describe the human motion trajectory.
