说明：  内含M文件 利用对数比实现，两幅多时空SAR图像变化差异图 (Logarithm figure than the implementation differences )

傅里叶变换的基本概念介绍和应用，做计算和频谱分析时蛮有用的。(fourier transform)

说明：  基于改进JPEG-LS算法的遥感图像近无损压缩专利，由航天五院508所申报，很详细的介绍了算法和fpga的实现(Improved JPEG-LS algorithm near lossless compression patent, the space the five branches of 508 reporting, a detailed explanation of the algorithm and implementation fpga)

通过邻域搜索法对一个相机拍摄的序列图像中圆形非编码标志点进行匹配(Neighborhood search method by camera on a circular non-coding sequence of images to match landmarks )

结合维纳滤波的小波降噪方法，滤波效果很好(Combination of Wiener filtering of wavelet noise reduction method, filter works well)

自己编写fft2和ifft2程序并进行快速傅里叶变换试验(fft2 and ifft2)

图像处理之Matlab特征提取和表达-一些规则图形的特征提取(Matlab feature extraction and expression in image processing - feature extraction of some regular patterns)

水印攻击测试程序optimark。 这个比stirmark更全面测试水印程序，很好用(Watermark attack test program optimark. This more comprehensive test than stirmark watermark program, very good use)

实现图像匀光，实现了MASK（马斯克）和Wallis匀光算法(附带参考文献)。(Image dodging, the MASK and Wallis dodging algorithm (with references).)

无线传感器网络，泛洪算法。每一轮次每个节点向中心节点发送数据。最后的生成图像为节点的死亡数。(Wireless sensor networks, the flooding algorithm. Each round, each node sends data to the central node. The final generated image is the node numbers of death.)
