预处理

计算图像的质心，用图像的算发进行操作。这样可以有效的算出图像的质心(The centroid of the calculated image, with an image of the operator hair operation. This can effectively calculating the image centroid)

直方图特征的计算，包括方差，峰度，熵值等。(Histogram of the characteristics of the calculation, including the variance, kurtosis, entropy and so on.)

视频读取并提取目标背景 背景要求是静止的 效果很好(Video read and extract the target background static background requirements are well)

使用Matlab生成一维光栅条纹，可用于结构光三维重建。(Matlab Generate One Dimensional Grating)

说明：  PCA图像融合算法，提取主成分来对图像进行融合,感兴趣的可以看看。(Principal component analysis Image fusion algorithm, extraction of principal components to image fusion.Those of you who are interested can take a look.)

说明：  二维功率谱密度计算程序 使用傅里叶变换，可以计算功率谱密度(Two dimensional power spectral density calculation program using Fourier transform)

基于matlab的图像处理边缘提取程序，包含各种常用的边缘提取方法。(Matlab image processing based on edge extraction process, contains a variety of commonly used edge detection methods.)

jpeglib的库文件，方便实现很多关于jpeg的操作，例如格式转换等等。(jpeglib the library file to facilitate the achievement of the operation of a number of jpeg, for example, format conversion and so on.)

使用fdtd算法的人都知道这是初学fdtd的入门程序,很简单的程序但是能起到很重要的作用哦()

说明：  对图像纹理特征进行提取，包括灰度共生矩阵、Lbp、小波等(Texture feature extraction of image, including gray level co-occurrence matrix, Lbp, wavelet and so on)
