Summary:Video-based tracking of contours on the human body has been shown to be useful for many applications, including gait and gesture recognition, posture estimation, and activity analysis. We present a contour tracking method that incorporates a novel edge feature and fuzzy contour template. We apply our method in tracking the motions of older adults exercising in a gym environment. The output of our system is a dynamic fuzzy representation of the spine angle of the subject. We show that the method described in this paper is capable of tracking contours even in cases where human silhouette extraction is poor.
