Description: This toolbox provides some functions for manipulating planar, closed splines to implement image or video segmentation by means of deformable (or active) contours. Contour topology is managed in a way that should allow changes similar to what can be observed with level sets (merging and splitting but no hole creation). Several objects can be segmented simultaneously in several frames. -This toolbox provides some functions for m anipulating planar. closed spline to implement image or video segm entation by means of deformable (or active) con tours. Contour topology is managed in a way that should allow changes similar to what can be obse rved with level sets (merging and splitting but no hole creation). Several objects can be segme nted simultaneously in several frames.

Description: 曲线拟合函数
三个函数，SPLine 调用另外两个。用时候直接调用SPLine函数，入口pList是已知离散点链表，pDestList是生成的点的链表。SM是在两个点中间插入点的数目，continue=0是采样点无规律，要求生成闭合曲线。-Curve fitting function of the three functions, SPLine call the other two. Spline used when a direct call function, the entrance is pList list of known discrete points, pDestList point is generated list. SM is based on two points between the number of insertion point, continue = 0 is a random sampling point, the requirements to generate closed curves.

Description: 数控系统中经常会用到样条插值，对于不封闭曲线，一般的样条插值，就能解决，但对于封闭曲线，首尾控制点的处理不当，传统的增加控制点的方法经常会出现不平滑，甚至锐角，本文就应用埃尔米特插值解决这一问题，并在Visual C++上进行仿真实现。-CNC systems are often used in spline interpolation, for non-closed curve, the general spline interpolation, can be solved, but for closed curves, head and tail control point was mishandled, the traditional method of increasing control points are often that there is no smooth, or even an acute angle, this paper on the application of Hermite interpolation to solve this problem, and in Visual C++ on Simulation.
