说明：  这是CA码的捕获过程仿真，这能帮助我们更好的理解CA的捕获(This is the CA code capture process simulation, which can help us a better understanding of the capture of the CA)

EM 算法是求参数极大似然估计的一种方法，它可以从非完整数据集中对参数进行估计，是一种非常简单实用的学习算法。这种方法可以广泛地应用于处理缺损数据、截尾数据以及带有噪声等所谓的不完全数据，可以具体来说，我们可以利用EM算法来填充样本中的缺失数据、发现隐藏变量的值、估计HMM中的参数、估计有限混合分布中的参数以及可以进行无监督聚类等等。(Expectation Maximization image segmentation Input: ima: grey color image k: Number of classes Output: mask: clasification image mask mu: vector of class means v: vector of class variances p: vector of class proportions )

说明：  对仿真的非平稳信号进行Hilbert-Huang变换，分析信号的时频特征。(The simulation of non-stationary signals, Hilbert-Huang transform analysis of time-frequency characteristics.)
