By using the transfer matrix of the beam propagation,the movement of the low-order nonlinear ghost image s was calculated when high-power Gaussian laser beam passes through the single convexo-convex lens,the single concavo-concave lens and the 4F system and then the movable rules were analyzed.

采用矩阵光学方法，计算了高功率高斯光束通过单个凸透镜、单个凹透镜及 4F系统时低阶非线性鬼像的移动，并分析了其移动规

A fixed reference point on the concave side of a conic section.

圆锥截面凹面的固定参考点。

It modified some terms of the initial formula, which made the snake model not only precisely extract the edge of the protruding object in images but also approach to the concave part of the edge. It introduced exterior sanction energy, which could adaptively change its value to enlarge suction, so that control points could quickly constringe to the real contour without relying on the initial contour. Combined with pattern matching, this new method could increase the precision of transferring the result of edge extraction from one slice to another.

通过调整原始公式的一些参数使得该模型不但能精确地提取图像中的凸形物体的边缘，而且能够接近边缘的凹陷处；引入自适应改变大小的外部约束能量来增大外能的吸引范围，使控制点能够不依赖于初始轮廓而快速地收敛到目标的真实轮廓；结合匹配技术，提高边缘提取结果层间传递的精度。
