Three numerical calculating schemes of realizing the curvature motion formula in curve evolving are discussed, including explicit scheme, semi-implicit scheme and median filter scheme.
探讨了三类实现曲线演化的曲率运动方程的数值计算方案：显示方案、半隐式方案和中值滤波方法。

And two classes of semi-explicit difference schemes are also established by introducing a dissipative term, they are unconditionally stable and can be calculated explicitly.
并用引入耗散项的方法建立了两类半显式差分格式，它们是无条件稳定的且可显式地进行计算。

Based on this semi-discretized scheme, the multistep explicit and the one step implicit scheme can be established. The results given by model problems show that the present scheme possesses h…
