Abstract

Active contours are deformable energy minimizing curves controlled by internal energy and external energy. The internal energy is constraint to preserve a smooth curve, and the external energy guides the curve towards image features. B-spline representation of active contours can be of great benefits in the segmentation and description whose shape is characterized by its defining polygon or control points. Menet et al proposed B-spline representation of active contours based on finit difference method[3]. In this paper, we propose a piecewise cubic B-spline representation of active contours based on dynamic programming. The method is simple and efficient by comparing over finite difference method.
