图片极坐标转换,可实现极坐标转换，以及求傅里叶变换(Picture polar coordinate conversion, convert polar coordinates can be realized, as well as seeking the Fourier transform)

高光谱图像MNF算法，实现高光谱图像的去噪，注释详尽(Hyperspectral image MNF algorithm to achieve denoising hyperspectral images, detailed comments)

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)

sift图像匹配的纯matlab代码,研究图像配准的可以用这个，配准图像效果较好！！(sift pure image matching matlab code of image registration can use this, the image registration is better! !)

小波包变换去噪和滤波去噪的word，可以直接剪切到MATLAB。有分析(Wavelet Packet Denoising and filtering denoising word, you can cut directly to MATLAB. Some analysts)

通过GDAL读取常用遥感影像，如img，tiff，可实现读取显示和雷达影像处理的一些基本算法(Read through GDAL common remote sensing images, such as img, tiff, read the display and radar can achieve some of the basic image processing algorithms)

1.打开左右两张影像2.Harris算法提取同名点3.显示提取同名点（若要进行下一步匹配则不建议显示，这里只是用于查看是否提取出）4.相关系数匹配（只在找出的同名点内匹配）5.LSM最小二乘匹配（先进行粗匹配，再精匹配）(1 Open the left and right images 2.Harris algorithm to extract two tie points 3 shows the extraction of corresponding points (not recommended to proceed to the next match show, here is used to see if extracted) 4. Correlation coefficient matching (just looking match within a point of the same name) 5.LSM least squares matching (rough first match, then fine match))

图象的冲击滤波程序,用于图象增强,用MATLAB语言编写(image filtering impact procedures for image enhancement, using MATLAB language)

说明：  SAR运动目标成像，包含了多个点目标，结果比较清晰(SAR Moving Target Imaging)
