PCA的步骤： 1 先将数据中心化； 2 求得的协方差矩阵； 3 求出协方差矩阵的特征值与特征向量； 4 将特征值与特征向量进行排序； 5 根据要降维的维数d’,求得要降维的投影方向； 6 求出降维后的数据； (PCA steps: 1 of the first data center 2 covariance matrix obtained 3 obtained covariance matrix eigenvalues and eigenvectors 4 eigenvalues and eigenvectors will be sorted 5 according to the dimension of dimension reduction d ' , seek to reduce the dimension projection direction 6, the data obtained after the dimensionality reduction )

多尺度熵matlab计算程序，应用于信号分析和处理(multi-scale entropy)

kin Pixel Likelihoods and Skin Detection ----------------------------------------------- This Matlab code was developed for skin pixel detection in general imagery. Non-parametric histogram-based models were trained using manually annotated skin and non-skin pixels. A total of 14,985,845 skin pixels and 304,844,751 non-skin pixels were used.

伪码调相雷达是相位编码雷达的一种，所谓的相位编码雷达就是用码字调制载频信号,通常码字的选择在某种意义上决定了其性能和处理的方式，相位编码根据其调相码字制式的不同，可分为多相编码和二相编码，根据调相码字有无周期性,可分为随机码调相和伪随机码调相。相位编码中比较常用的是二相码，二相码即采用两个相位状态对载频信号进行相位调制。在相位编码中，伪随机码由于其良好的性能和易实现等特点而得到了广泛的应用。(Pseudo phase coded pulse radar signal processing.)
