轮轨接触CONTACT程序，可以用来计算轮轨磨耗(Wheel-rail contact CONTACT procedures can be used to calculate the wheel-rail wear)

说明：  本程序是基2的时间抽取FFT变换，可以将信号从时域转换到频域。(This procedure is the base 2 time extraction FFT transform, can transform the signal from time domain to frequency domain.)

说明：  共享主成份尺度不变变换PCA-SIFT代码，用于SAR图像配准，希望对各位雷达爱好者和SAR工作者有用！(Principle component analysis, PCA- Scale invariant feature transform-SIFT used for SAR processing. )

提取视频中的图片，每一帧的信息，把视频分为图片信息(get picture of video)

图象降维算法,比如有名的LLE,PCA,ISOMAP......等,对研究图象分析的研究人员有很大的帮助(image dimensionality reduction algorithms such as the famous LLE, PCA, ISOMAP .... Image analysis of the study researchers will be very helpful )

空间点云的三角化，已通过调试，大家共同学习(Point cloud of the triangular space, and have passed testing, we learn together)

图像去躁，图像求反，动态范围压缩，直方图均衡化，高通滤波器处理(Image denoising, image inversion, dynamic range compression, histogram equalization, high pass filter processing)

一种用三维重建的matlab代码，有实验结果图(A three-dimensional reconstruction of the matlab code, with experimental results)

IDL读取txt，txt第一列是纬度，第二列是经度，第三列是DN值， 坐标转行列号 ，并以图像的形式输出(IDL reads TXT. The first column of TXT is latitude, the second column is longitude, and the third column is DN value. The coordinate turns the line and column number and outputs it in the form of image)

说明：  这是一个用VC++写的用于数控编程的系统,内含仿真器和说明书,请不要用于商业行为。(This is a VC was made for NC programming system includes simulators and brochures, please do not for commercial activities.)
