We searched each grid for picking up the 3D point position on which the quantity was equal to the designated contourlevel. Then these special points were connected in some contours according …
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.
