Aiming at the disability of parametric active contour models, people proposed Level Set Methed.
针对参数活动轮廓模型的缺点，学者们提出了水平集模型。

A new feature level fusion method of target's contour was proposed, which minimizes norm's square of the difference of control point vectors of convergent dynamic contours in two modal images.
It has a great significance in production of part with little curvature big contour, such as wings of plane, it enhance the productivity and level of craftwork.
