说明：  matlab实现人眼精确定位 实现效果良好(Accurate eye location by MATLAB)

用于对灰度图像的双边滤波，程序简单易懂，还有很强的可开发性(Bilateral Filtering)

抽取子图像: 通过一个随机混沌标签序列从原图像中抽取 对子图像加密:小波变换 ,在高频部分加密 重构原图，把加密好的子图像重新放回到原图像中 (from sub-images : a random chaotic sequence label from the original image from a tradition image encryption : wavelet transform, the high-frequency part of remodeling the maximum encryption, encrypted good son to re-up images back to the original image)

图像拼接 sift 特征点，两幅图像进行拼配 拼接，先找找出特征点匹配(The image stitching， sift feature points, two images blending splicing find someone to identify the characteristics of point matching)

水下图像增强方法，可以对退化的水下图像进行图像复原，但是对太模糊的水下图像不适用。(a method of underwater images enhancement)

卡尔曼滤波是一种高效率的递归滤波器(自回归滤波器), 它能够从一系列的不完全及包含噪声的测量中，估计动态系统的状态。(Calman filtering is an efficient recursive filter (autoregressive filter). It can estimate the state of dynamic system from a series of incomplete and noisy measurements.)

循环理论相关MATLAB程序：滚动轴承仿真信号的产生(加噪声干扰)(Cyclostationary related)

通过高斯核密度估计计算多元变量之间的互信息熵(The mutual information entropy between multivariate variables is calculated by Gaussian kernel density estimation)

说明：  包括IHS,PCA Fusio,加权图像融合算法的Matlab源代码！主要运用在GSM中卫星图像处理，里面有例子图片，可以清晰的看见处理效果！(including IHS, PCA Fusio, the weighted image fusion algorithms Matlab source code! The main use of the GSM satellite image processing, there are examples of photographs, can clearly see the effect!)

说明：  读取nc、hdf文件，进行数据分析（趋势分析、逐步线性回归等）(To read nc and hdf and do data analysis.)
