蒙特卡洛随机相位屏 用于模拟大气湍流 只需要调节一定的参数(Monte Carlo random phase screen is used to simulate atmospheric turbulence only need to adjust certain parameters)

MATLAB编译，主要是与船舶相关的编译程序，简单方便，易于使用。(MATLAB compilation, mainly related to ship compiler, simple, convenient and easy to use)

模糊聚类方法，用相关系数法构造模糊相似关系矩阵r，构造了模糊等价评判矩阵，为了方便下载者使用，把代码进行了优化，可直接把矩阵带进去使用。(Fuzzy clustering method, using the correlation coefficient method to construct the fuzzy similarity relation matrix r, construct a fuzzy equivalence evaluation matrix, in order to facilitate the download to use, the code has been optimized, can go directly to the matrix with the use.)

滤波器程序，通过低通滤波器对数据进行滤波处理(Low-pass filter , mainly for time series filtering process .)

图像特征提取以及匹配，sift代码。可用于图片检索中，同比SURF，其算法可以较好的识别图像中文字(Image feature extraction and matching, sift the code. Can be used for image retrieval, up by SURF, the algorithm can better identify the image text)

RGB to gray scale conversion of image.

This project will do encryption by reserving room before encryption for better performance of the compressed image

The network weights are adjusted during the online implementation. The method used is based on the gradient descent method (GD), which is a simple and fast method for online adaptation.
