著名的墨西哥草帽三维编程，matlab语言。(Well-known Mexican hat three-dimensional programming, matlab language.)

对图像进行欠采样，然后利用OMP 进行重构，其中用到了小波矩阵进行稀疏(The image is undersampled and then reconstructed by OMP, in which the wavelet matrix is used for sparsity.)

一个由matlab编写的从多视点拍摄的图像计算Visual Hull的简单的演示程序，基于空间体积的方法求物体的Visual Hull，对实现由多视点图像求Visual Hull的过程可以起到借鉴作用(Matlab prepared by a multi-viewpoint images of the Visual Hull calculate simple demo program, the method of space-based volume objects for Visual Hull, the realization of multi-viewpoint image for Visual Hull of the process can play a useful reference)

二维图像的基本处理，包括imfilter等matlab库函数的移植(The basic two-dimensional image processing, including imfilter matlab library function such as migration)

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.)

说明：  三维重建是指对三维物体建立适合计算机表示和处理的数学模型,是在计算机环境下对其进行处理、操作和分析其性质的基础,也是在计算机中建立表达客观世界的虚拟现实的关键技术。(Three-dimensional reconstruction refers to the establishment of a mathematical model suitable for computer representation and processing of three-dimensional objects. It is the basis for processing, manipulating and analyzing their properties in the computer environment. It is also the key technology for establishing a virtual reality to express the objective world in the computer.)

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)

迭代最近点点云配准算法的matlab实现，最经典的算法(Iterative Closest little cloud registration algorithm matlab realize, the most classical algorithm)

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!)

nsct 非下采样的contourlet变换的matlab工具箱,很详细的(nsct non-sampled contourlet transform Matlab toolbox, a very detailed)
