主动轮廓线模型引入高层知识，在处理局部间断的边缘时，具有优于传统轮廓提取方法的提取效果。

With the introduction of high level information, Snake model has more satisfactory effects than what gained by the traditional method when dealing with disconnected edges in the image.

实验结果表明，初始轮廓线的设置应避免跨越能量极小值，此时可以得到比较好的提取效果。

The experimentation proves that the position of the initial edge should avoid acrossing the fields between the minimum of the energy, so that a better effect of edge-detection can be given.

传统的基于轮廓线三维重建方法中，直接采用由序列轮廓线生成的平面三角片拟合曲面，重建的效果和表达的信息均有限。

In traditional method, flat triangles produced by listed contour data are used directly to fit the surface in which the reconstructed effect and the expressive information are limited.
