| Abstract(in English) | Marker-less human body measurement is a key technology for a variety of fields such as sports science or the multi-media industry. In this report, we first propose a method of extracting a moving human body from image sequence of natural scene based on subtraction and then calculating its contour using an active contour model(snakes). We then describe a hierarchical part decomposition method of human body contours. In this method, the human body is regarded as an articulated object and high-curvature points on the contour are used to divide the body region into multiple characteristic elements without any model of link parameters of the object. We finally show experimental results with synthetic and real images to validate the proposed method. |
