如何检测显著峰？ [英] How to detect significant Peaks?

问题描述

我有是坐标点的表（X，Y-显示为图表系列）。现在，我检查了如何检测峰。 对于每一个点（P）我要检查是否（PY> P-1.Y＆功放;＆功放; PY> P + 1.Y）。如果是，它必须是一个峰值。

I've got a table with coordinate-points (X,Y-shown as a Chart-Series). Now I checked out how to detect peaks. For each Point (P) I have to check whether (P.Y > P-1.Y && P.Y > P+1.Y). If it is, it must be a Peak.

但是，如果我想只得到了整个图形的真正显著峰？我的猜测是，我会NEET某种阈值。还有什么比这道门槛是或者我应该如何改变条件峰？

But what if I want to get only the really significant peaks for the entire graph? My guess is, I would neet some kind of threshold. What could this threshold be or how should I change the condition for peaks?

在此先感谢，

推荐答案

最简单的事情来到我的脑海里：

The simplest thing coming to my mind:

public bool IsPeak(Point prev, Point aPoint, Point next, float threshold)
    {
        return aPoint.Y - prev.Y > threshold && aPoint.Y - next.Y;
    }
