说明：  遥感图像运用6S工具来进行大气辐射校正处理(Atmospheric Radiation Correction Processing Using 6S Tool for Remote Sensing Images)

自己编写的单应性矩阵的求法，按照张正友的论文进行编写的。希望有用。(I have written the homography method, according to Zhang Zhengyou papers prepared for. I hope useful.)

图像分割经典算法GraphCut的实现代码，亲测可用。(An implementation of GraphCut Algorithm, which is a classical method in image segmentation field.)

分析了合成孔径雷达的模糊度问题及其对图像质量的影响, 详细描述了模糊度的 表达式, 分析了不同系统参数对模糊度的影响, 对所谓的重影现象作了定量分析(Analysis of synthetic aperture radar ambiguity problems and their impact on image quality, a detailed description of the fuzzy degree of expression of the different system parameters on the degree of influence on the so-called ghost phenomenon analyzed quantitatively)

本例中主要使用四个区模糊函数对图像去模糊，分别是deconvwnr、deconvreg、deconvlucy、deconvblind。这四个函数分别适合不同的情况，对模糊图像的恢复效果也不同(In this case the main use of the four areas on the image to the fuzzy ambiguity function, respectively deconvwnr, deconvreg, deconvlucy, deconvblind. These four functions are appropriate for different situations, the recovery of the blurred image effect is different)

说明：  为图像分别加高斯噪声和椒盐噪声，采用中值滤波方法对受噪声干扰的图像滤波，窗口分别采用3*3,5*5,7*7；(Gaussian noise and salt and pepper noise are added to the image respectively. The median filtering method is used to filter the image disturbed by noise. The window is 3 * 3,5 * 5,7 * 7;)

利用数学形态学对云层背景下的目标进行检测识别，有两种方法。 (Using mathematical morphology of clouds in the context of target identification, there are two ways.)

说明：  基于局部Fisher准则的非线性核Fisher辨别分析，应用于有监督的特征提取与高维数据的有效降维。(Kernel Local Fisher Discriminant Analysis for Supervised Dimensionality Reduction.)

双树复小波变换的图像融合程序代码，有图可编译运行(DTCWT image fusion)

基于最大类间方差准则的阈值分割算法。其基本思想是对像素进行划分，通过划分得到的各类之间的距离达到最大，来确定合适的门限。(Based on the maximum between-cluster variance criteria threshold segmentation algorithm. The basic idea is to divide pixels, obtained through the division of the distance between the various types of maximum, to determine the appropriate threshold.)
