经过二维混沌序列构成的相位板的双随机相位系统再经过菲涅尔变换后得到的加密解密(Encryption and decryption after Fresnel transformation of the double-random phase system of a phase plate composed of two-dimensional chaotic sequence)

好用地 matlab版本地 用hough变换进行直线提取地程序，提取最长地直线，以后会改进，可以提取累计矩阵中，局部峰值点地直线！(good land use Matlab version hough transform line extraction procedures. to extract the longest line, it will improve, can extract accumulated matrix, partial to the peak point straight!)

用FCM 对自然图像 sar图像以及纹理图像进行快速分割 ，用一维和二维直方图分别对图像进行特征映射 从而快速的对图像进行分割 包含结果截图 (By FCM sar image of natural images quickly and texture image segmentation, with one-dimensional and two-dimensional histogram of the image feature maps were so fast image segmentation screenshot contains the results)

基于路径跟踪法的insar相位解缠的整个程序(tracking method based on the path of insar Phase Unwrapping the entire process)

高斯平滑滤波实例，高斯滤波实质上是一种信号的滤波器，其用途是信号的平滑处理，我们知道数字图像用于后期应用，其噪声是最大的问题，，由于误差会累计传递等原因，很多图像处理教材会在很早的时候介绍Gauss滤波器，用于得到信噪比SNR较高的图像（反应真实信号）。 (Instance of the Gaussian smoothing filter, Gaussian filter is essentially a signal filter, its purpose is to smooth processing of the signal, we know that the digital image for the late application, the noise is the biggest problem, the error accumulated transfer reason, a lot of image processing textbooks will be introduced at an early Gauss filter for higher SNR of the image (real response signal).)

说明：  此代码是由FCM算法改变的且用于图像分割，比FCM算法对图像的分割的效果更好(This code is changed by FCM algorithm and is used for image segmentation, which is better than FCM algorithm for image segmentation)

主成分分析ppt。对主成分分析的细节讲述的很清楚。(Principal component analysis ppt. The details of the principal component analysis described in very clear.)

一个很好类子来说明类模板的使用，可以比较明了类模板的使用方法，最好进行单步调试(use of class template )
