用于计算在三维点云处理过程中的局部点云面积估算，精度很高。(Used to calculate the three-dimensional point cloud processing local point cloud area estimation accuracy is very high.)

四步相移法程序和最小二乘法相位解包裹程序，已经验证，此方法比较不错。(Four step phase-shift method program and least squares phase solution package, have validation, this method is good. )

低秩的求解 denoise an image by sparsely representing each block with the already overcomplete trained Dictionary, and averaging the represented parts. Detailed description can be found in "Image Denoising Via Sparse and Redundant representations over Learned Dictionaries(low rankdenoise an image by sparsely representing each block with the already overcomplete trained Dictionary, and averaging the represented parts. Detailed description can be found in "Image Denoising Via Sparse and Redundant representations over Learned Dictionaries)

meanshift图像跟踪算法，实现目标物体的连续跟踪(meanshift image tracking algorithm to achieve continuous tracking of the target object)

图像去噪，是目前图像处理领域对高斯白噪声效果最好的去噪算法(image denoising)

生成voronoi图,生成voronoi 2D图形。(creat voronoi diagram)

相机标定过程中，对初始得到的内外参数的进行整体优化，从而得到最佳内外参数的程序(Camera calibration process, the overall optimization of the initial parameters obtained inside and outside, resulting in the program inside and outside the parameters of the best)

绘制出lorenz系统的三维图，初始值和角度可以调整，时间长度也可以自己调整。(Three-dimensional map drawn lorenz system, the initial value and the angle can be adjusted to the length of time can also make their own adjustments.)

这是一篇关于超声相控阵二维面阵实现三维成像的文章，很不错。(This is an article on ultrasonic phased array two-dimensional array of three- dimensional imaging article, great.)

说明：  本方法采用pca进行特征提取，knn分类器进行人脸识别。(The method of feature extraction using pca, knn classifier for face recognition.)
