python 计算机视觉 1.3.4直方图均衡化 进行归一化的一个非常好的方法,并且可以增强图像的对比度。 在这种情况下,直方图均衡化的变换函数是图像中像素值的累积分布函数(cumulativedistributionfunction,简写为cdf,将像素值的范围映射到目标范围的归一化操作)。 下面的函数是直方图均衡化的具体实现。 该
累積分布関数(CDF: Cumulative Distribution Function)とは 確率変数Xがある値x以下(X <= x)の値となる確率です。 例えばサイコロを投げたときに「出る目が4以下となる確率」や「出る目が4から6の目が出る確率」といった、ある範囲の確率を求めるときに使用します。 確率質量関数(PMF: Probabi...

We use code from the Python package emd (Quinn et al., 2021) to perform all EMD-related calculations. We then rescale the variances of the IMFs of the time series as suggested in (Flandrin et al. 2005; Wu and Huang, 2004). The variance for an IMF that has zero mean by definition...
