计算图像处理中的评价指标NPCR和UACI(Calculate the evaluation indexes NPCR and UACI)

非精确ALM解决PCA算法的例子，用后效果不错，发上来分享。(This matlab code implements the inexact augmented Lagrange multiplier method for Robust PCA.)

说明：  利用双线性插值法，来对图像进行放大或者缩小的操作(Bilinear interpolation is used to enlarge or shrink the image)

快速傅里叶变换的C实现，采用新的倒序算法，程序代码只有一百多行，就要以实现千个采样点的计算(Fast Fourier Transform of C realized, the introduction of a new reverse algorithm, program code, only more than 100 lines, it is necessary to achieve the 1000 sampling points calculation)

直方图均衡化处理编程指南及实验报告，数字图像处理及应用，阮秋琦教授，北京交通大学（资源分享）。(Histogram equalization processing programming guide and laboratory reports，Application of digital image processing and Beijing Jiaotong University, Professor Ruan Qiuqi)

使用GDAL库，用于遥感影像的特征点提取(Using the GDAL library, used for remote sensing image feature point extraction)

主要是对视网膜图像进行血管分割，效果还不错(Primarily on retinal vascular image segmentation, the effect was not bad)

说明：  用C语言实现图像的平滑，锐化及双线性内插算法的实现，效果很好(Using C language to achieve image smoothing, sharpening and bilinear interpolation algorithm to achieve good results)

该算法是局部线性嵌入的算法，代码无误，已运行，并且附带数据集，可以使用，非常实用。(The algorithm is locally linear embedding algorithm, the code is correct, has been running, and with the data set, you can use, very practical.)
