平滑曲线的算法 [英] algorithm to smooth curve

问题描述

我有很多点的曲线，导致GUI级别的速度变慢。我想应用一种算法，以消除彼此之间距离太近的相邻点（就值而言，因此可以认为是无用的）。

I have a curve with a lot of points, resulting in a slowing down at GUI level. I would like to apply an algorithm which remove adjacent points which are too close of each other (in term of values, and so can be considered useless)

有没有著名的算法能做到这一点？我正在使用C＃和ZedGraph

Is there any famous algorithm to do this ? I'm using C# and ZedGraph

推荐答案

您可以使用 Douglas-Peucker 算法可减少点数并保存曲线形状。可以在此处

You can use Douglas-Peucker algorithm to reduce number of points and save the curve shape. C# implementation can be found here
