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)

噪声估计法，先定位噪声点，再实行去噪处理(Noise estimation method, first locate the noise points, then implement denoising.)

计算指纹方向场的代码。。。。。。。。。。。。(code for computing orientation of fingerprint )

说明：  用于SAR图像的相干斑抑制，内有增强Lee滤波，增强Kuan滤波，增强GammaMap滤波算法，还有等效视数，边缘保持指数的求法(For speckle suppression of SAR images, there are enhanced Lee filtering, enhanced Kuan filtering, enhanced GammaMap filtering algorithm, and the calculation of ENL and EPI.)

基于小波包变换的去噪处理 全局阈值去噪图像 对图像进行平滑处理以增强去噪效果（中值滤波）(Denoising based on wavelet packet transform global threshold denoising image smoothing image enhancement and denoising effect (median filtering))

用于对图像进行分割的算法的一种，对部分类型图像处理较好 (For the image segmentation algorithm a kind type of image processing on the part of good)

基于Matlab实现的傅立叶梅林变换的源程序代码(Based on Matlab implementation of the Fourier transform of the source code Merlin)

一个图片浏览器程序，除了基本的图片浏览功能外，还包括图像特效处理功能和特效处理算法。(An image browser program, in addition to basic image browsing functions, including image effects processing capabilities and effects-processing algorithms.)

说明：  基于opencv平台编写的单目相机标定程序，使用的张正友的方法，只要准备十二张单目相机拍摄的棋盘格的图片就可以标定出单目相机的焦距等参数，建立单目相机坐标系。可以用于机器视觉测量中，也可以用于双面相机标定的前一步，精度很高。(Based on the monocular camera calibration program compiled by the OpenCV platform, the method of Zhang Zhengyou is used to calibrate the focal length and other parameters of the monocular camera and establish a monocular camera coordinate system as long as 12 pieces of chessboard pictures taken by the monocular camera are prepared. It can be used in machine vision measurement, and it can also be used in the previous step of the calibration of the double-sided camera, with high precision.)
