下面我将详细解释 find_peaks 函数的原理。 首先,我们需要明确什么是“峰值”。在数据中,峰值是指高于其相邻值的点。例如,在以下数据中: 1, 2, 3, 7, 6, 5 数字7 是峰值,因为它比其相邻的 6 和 5 都高。 find_peaks 函数通常使用以下步骤来找到峰值: 1、初始化 :首先,我们需要一个数据集。这个数据...
peaks, _ = find_peaks(x, height=3) print(peaks) # 输出: [2 3 7] 在这个示例中,我们查找数组x中高度至少为3的峰值,并打印出它们的索引。 作者:PPPANLS

As stated in the documentation, scipy.signal.find_peaks works for 1D signals. There are many attempts of similar function for 2D arrays, such as https://stackoverflow.com/questions/3684484/peak-detection-in-a-2d-array, https://stackoverf...
