hello

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)

在matlab开发环境中，使用模糊C均值聚类的方法对数据进行聚类(In the Matlab development environment, the use of fuzzy C-means clustering methods for data clustering)

说明：  基于相位梯度法PGA的 Matlab 估计相位误差 估计多普勒中心(Estimation of Phase Error and Doppler Center by PGA MATLAB)

维纳滤波与盲卷积算法代码，用于图像处理去燥 清晰化处理，自带图像还有附录讲解(Wiener filter and blind convolution algorithm code for image processing to dry clear processing, comes with the image there are appendix to explain)

基于Hough变换和基于Radon变换的直线检测算法代码(source code of two straight line detection algorithm (based on Hough Transform and Radon Transform))

平台基于visual studio2015，使用opencv函数实现中值滤波，进行图像处理(median blur based on opencv)

说明：  实现了三种图像匹配算法 1：归一化互相关匹配算法 2：基于Hausdorff距离的图像匹配算法 3：图像不变矩匹配算法(Three matching algorithms to achieve 1: normalized cross correlation matching algorithm 2: the image matching algorithm based on Hausdorff Distance 3: Image Invariant Moment Matching Algorithm)

基于混沌理论和量化方法实现一种针对灰度图像的鲁棒水印算法。(Based on chaos theory and quantitative methods to achieve a robust watermarking algorithm for grayscale images.)

运用harr特征+SRC（稀疏表示）分类实现的一种车辆检测方法，文件中提供了训练和测试车辆图片。由于时间原因，所用haar特征没有优化，维度过高，导致滑窗框图过慢，本代码只输出效果统计数据，以供大家参考学习稀疏表示在车辆检测中的应用。(Using harr feature+SRC (sparse representation) classification to achieve a vehicle detection method, the paper provides a training and test vehicle picture. Due to time reasons, the use of haar feature is not optimized, high dimension, resulting in sliding sash figure is too slow, the effect of the code only output statistics for your reference learning sparse representation in the vehicle detection.)

本m文件实现的是正面人脸的提取，基于YCbCr空间肤色区域提取和形态学的处理(this document is the realization of the right face extraction, YCbCr color space based on regional extraction and processing of morphological)
