| 摘 要： | 1. Introduction The active contour model (also called snake) was first proposed by Kass 1] and can be used in many image analysis and computer vision applications such as edge detection, motion tracking, image matching, and 3-D reconstruction. A snake is a energy-minimizing curve controlled by internal and external forces. Internal forces act as a smoothness constraint, and external forces guide the snake toward image features that are of interest. B-spline representation of active contour c…

| Abstract: | A B-spline active contour model based on finite element method is presented, into which the advantages of a B-spline active contour attributing to its fewer parameters and its smoothness is built accompanied with reduced computational complexity and better numerical stability resulted from the finite element method. In this model, a cubic B-spline segment is taken as an element, and the finite element method is adopted to solve the energy minimization problem of the B-spline active contour, thus to implement image segmentation. Experiment results verify that this method is efficient for B-spline active contour, which attains stable, accurate and faster convergence. |
