A discrete dynamic model for de?ning and tracking contours in 2-D medical images is presented. An active contour
in this objective is optimized by a dynamic programming algorithm, for which a new constraint that has fast and stable
properties is introduced. The internal energy of the model depends on local behavior of the contour, while the external
energy is derived from image features. The algorithm is able to rapidly detect convex and concave objects even when the
image quality is poor.
