SBS-Threshold

清华大学本科生课程设计，实现平面点集的三角剖分！用外接圆测试剖分的正确性。算法执行速度较快，但存在狭长三角形！(Tsinghua University undergraduate courses designed to achieve the triangulation of the set of points in the plane! Circumcircle test the correctness of the split. Algorithms perform faster, but there is a long, narrow triangle!)

c 实现了以点阵表示的多边形的最小外接矩形，并求出其的面积。(c to achieve a in order to dot-matrix expressed of polygons of the minimum bounding rectangle, and calculated its of the area.)

3D点云拼接 ICP算法；可以实现出来 ；斯坦福的兔子点云数据(3D point cloud splicing ICP algorithm)

说明：  在matlab中读取stl切片文件，形成点云数据(Read STL slice file in MATLAB to form point cloud data)

说明：  在图像上画一条线，提取所在位置的像素。主要是用来观察横向异质性变化的。(Draw a line on the image and extract the pixels at the location. Mainly used to observe changes in lateral heterogeneity.)

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.)

绘制瀑布图通过matlab语言，绘制转子个频率点个时间点的幅值变化情况(Draw waterfall figure)

说明：  基于dwt的数字水印源代码,可以进行水印的嵌入与提取(Dwt-based Digital Watermarking source code can be embedded and extracted watermark)

基于二维照片的体素法三维重建程序，重建之前进行误差分析，效果还可以。(Voxel-based method two-dimensional picture reconstruction process, before reconstruction error analysis, the effect can be.)

自己编写的散斑生成算法，对于三维重建有很大的帮助(the generation algorithm of the speckle image， which is helpful for the three dimensional reconstruction)
