利用蝶形算法类似于FFT，利用先行再列实现二维DCT。速度很快。包含反DCT的代码。(similar to the use of butterfly FFT algorithm, the first re-use of 2D DCT out. Very fast. Contain anti- DCT code.)

控制测量是测绘专业的基础课程，这个课件是武汉大学老师编的课件，很实用(Control measurements are mapping the professional foundation courses, this courseware is Wuhan University teachers series courseware, very practical)

滤波反投影CT图像重建算法 filter-backproject reconstruction, including feldkamp (FDK) cone beam(Filter back projection algorithm for CT image reconstruction filter-backproject reconstruction, including feldkamp (FDK) cone beam)

改进的otsu算法，计算局部otsu的值确定局部小区域。对于光照不均匀图像处理有比较好的适应( Improved otsu algorithm to calculate the value of the local otsu determine the local small area. For uneven illumination image processing has a relatively good adaptation)

hough变换，用于直线和圆，椭圆的检测，很实用(hough transform for line and circle, ellipse detection, it is practical)

一个自适应的滤波处理的方法，可以对图像有很好的处理效果。(An adaptive filtering method of treatment can have a good image the effect of treatment.)

类似PChunter的内核工具。本工具是应用层的源码。适合内核新手(Similar PChunter core tools. This tool is the source application layer. Suitable for novice kernel)

说明：  对于单基地SAR，使用BP算法进行成像，展示回波信号幅度、相位、距离压缩后以及最后成像的图像。(For single base SAR, BP algorithm is used to image, which shows the amplitude, phase, distance compressed and final image of echo signal.)

这是一个数字图像处理的程序，能够实现目标检测与跟踪，事项了EM算法、是对原有的算法改进。(This is a program of digital image processing, target detection and tracking can be achieved, the matter of the EM algorithm, the improved algorithm is the original.)

This is surf(Speeded Up Features Robust) matlab code for detection keypoint and construct descriptor and matching
