英文摘要：

Image segmentation based on active contour model（ACM） is a hotspot in computer vision. Firstly, the mathematical model of ACM and the related numerical implementation are discussed. Secondly, two development models of ACM are summarized in contrast： parameter active contour model and geometry contour model. The comparative study of these two kinds of models and the deep discussion on the scope of image segmentation application and advantages and disadvantages of each kind of techniques are carried out. Finally, the directions of future development in ACM are pointed out.
