说明：  一个EM算法实现图像分割，可以实现彩色图像分割。(An EM algorithm is used for image segmentation.)

物理学系学生应用matlab，初尝试。 绘制静电场，偶极子电场分布图。(for students major in physics, the first attempt to relate matlab and physics. draw how the electronic field like.)

说明：  实现区间缩小，通过labview实现数字归一化(To achieve the interval reduction, through labview to achieve digital normalization)

pca算法，用于数据降维，注释非常详细清晰，(PCA algorithm, for data dimensionality reduction, clear and very detailed notes,)

主成分分析 （ Principal Component Analysis ， PCA ）或者主元分析。是一种掌握事物主要矛盾的统计分析方法，它可以从多元事物中解析出主要影响因素，揭示事物的本质，简化复杂的问题。计算主成分的目的是将高维数据投影到较低维空间。给定 n 个变量的 m 个观察值，形成一个 n ′ m 的数据矩阵， n 通常比较大。对于一个由多个变量描述的复杂事物，人们难以认识，那么是否可以抓住事物主要方面进行重点分析呢？如果事物的主要方面刚好体现在几个主要变量上，我们只需要将这几个变量分离出来，进行详细分析。但是，在一般情况下，并不能直接找出这样的关键变量。这时我们可以用原有变量的线性组合来表示事物的主要方面， PCA 就是这样一种分析方法。(Principal component analysis (Principal Component Analysis, PCA) or PCA. Is a statistical method to grasp the principal contradiction of things, it can be resolved diverse things out the main factors, revealing the essence of things, simplifying complex problems. The purpose of calculating the main component of high-dimensional data is projected to a lower dimensional space. Given n variables of m observations, forming an n ' m of the data matrix, n is usually large. For a complex matters described by several variables, it is difficult to know, so if you can grab something to focus on key aspects of analysis? If the main aspects of things just reflected on several key variables, we only need to separate out these few variables, for detailed analysis. However, in general, does not directly identify this critical variables. Then we can represent the major aspects of things with a linear combination of the original variables, PCA is one such analysis.)

Laws纹理策度是用来进行纹理分割的程序,这种方法很有用.(Laws degree texture strategy are used for texture segmentation procedure, this method useful.)

图像去躁，图像求反，动态范围压缩，直方图均衡化，高通滤波器处理(Image denoising, image inversion, dynamic range compression, histogram equalization, high pass filter processing)

自己编写的一个用于人脸识别2dpca程序，很好用的，里面有中文注释(I have written one for the face recognition 2dpca procedures, well used, which has Chinese Notes)

利用EM算法进行的彩色图像分割，利用EM算法进行的彩色图像分割(The use of EM algorithm for color image segmentation)

压缩包里面为2个程序，一个是悬链线模拟索的程序，一个是抛物线法模拟的索的程序(Compressed inside of two programs, one cable catenary simulation program, a parabolic law analog cable programs)
