Tracking moving contours using energy-minimizing elastic contour models
This paper proposes a method for tracking an arbitrary object contour in a sequence of images. In the contour tracking, energy-minimizing elastic contour models are utilized, which is newly presented in this paper. The proposed method makes it possible to establish object tracking even when complex texture and occluding edges exist in or near the target object. We also newly present an algorithm which efficiently solves energy minimization problems within dynamic programming framework. The algorithm enables us to obtain optimal solution even when the variables to be optimized are not ordered.
