可以对点云添加噪声，对从网站上下载的标准点云研究提供基础数据，比如研究去噪方法，可通过添加噪声形成基础数据(You can add noise to the point cloud to the standard point cloud research downloaded from the website to provide basic data, such as research de-noising method can form the basis of the data by adding noise)

离散小波变换(母小波采用db24)和FFT变换的混合算法，对谐波分量进行分析，求出各平稳谐波分量幅值及时变信号的发生时间(Hybrid algorithm of discrete wavelet transform and FFT transform analysis of the harmonic components, the calculated steady harmonic component amplitude and time-varying signal occurred)

修改过的pca-sift程序 可以正常运行(Modified pca-sift program runs)

MSE，最小均方误差,用于图像匹配，可用，亲测(MSE, minimum mean square error for image matching, available, pro-test)

实现彩色图像的N*N 中值滤波器，可选择滤波系数。(To achieve the N* N color image median filter, selectable filter coefficients.)
