点云特征提取 详细 实用 经典的讲述过程及方法FeatureExtractionFromPointClouds

usps数据库为标准手写数据库，此为mat数据文件，含训练集和测试(USPS database is a standard handwritten database, which is a mat data file, including training set and test)

能够实现土壤水分和光照度的数据的显示与保存(Data can be achieved degree of soil moisture and light display and preservation)

说明：  用滑动窗口中图像的灰度共生矩阵进行简单的2类纹理的分割.(sliding window of the gray image symbiotic matrix simple two types of texture segmentation.)

说明：  用小波的方法对图像进行二值化操作÷ 效果不错(wavelet methods of image binarization good operating results )

分割区域图像,好滴哦将按计划啊房价跌幅 安防科技来得及(for photo segemetation)

说明：  PCA图像融合算法，提取主成分来对图像进行融合,感兴趣的可以看看。(Principal component analysis Image fusion algorithm, extraction of principal components to image fusion.Those of you who are interested can take a look.)

说明：  计算凸包面积，点集Q的凸包是指一个最小凸多边形，满足Q中的点或者在多边形边上或者在其内。(Calculate convex hull area。The convex hull of point set Q is a minimum convex polygon, to meet the Q of the point or polygon or in its inside edge)

对于空间两个点云，利用经典的icp算法进行匹配(ICP fit points in data to the points in model. Fit with respect to minimize the sum of square errors with the closest model points and data points. )

对比BP，OMP，StOMP对自然图像的重构效果,输入图像是一幅256*256的lena图像，我们使用压缩采样后，再用上述三种方法对其进行重构，比较其结果，其中StOMP方法是用不同的阈值(Contrast to BP, OMP, StOMP effect on the reconstruction of natural images, input image is a 256* 256 lena image, we use the compressed sampled, and then reconstruct them the above-mentioned three methods to compare their results, which StOMP method is to use different thresholds)

Doris整个工程文件，包括利用Doris进行影像配准，干涉图生成，DEM生成，是对SAR影像干涉处理的绝佳代码(Doris whole project documents, including the use of Doris for image registration, interferogram generation, DEM generation, is an excellent SAR image processing code for intervention)
