二维CT投影仿真

说明：  采用水平集（level set）方法和mumford-shah图像分割模型的图像分割matlab源代码。(horizontal Collection (level set) methods and Mumford- shah Segmentation Model Image segmentation Matlab source code.)

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.)

这是一个图片配准的程序，能找出配准点，输入两张同一物体的照片，程序可找到两张图片中物体的相同点(This is a picture of the registration process, to help identify the registration point, the importation of two photographs of the same object, procedures can be found two photographs of objects in the same spots)

展开相位是物体表面三维形貌测量中一项关键技术，为了避免相位展开过程中的误差传播效应，Saldner和Huntlye等提出了时间相位展开方法。用matlab模拟了时间相位展开的方法(Expand the phase surface 3D topography measurement of a key technology in order to avoid the phase unwrapping process of error propagation effects, Saldner and Huntlye temporal phase unwrapping. Using matlab to simulate the temporal phase unwrapping method)

说明：  本编程用于求解点到曲面的距离，快捷便利。(Solving the Distance from Point to Surface)

立体匹配 asw算法实现 立体匹配经典局部算法(adapsive support weight algrithom)

K-D树源码，不错的空间查找算法，在三维重建和匹配中应用较多！(KD tree source, good space search algorithm, in the three-dimensional reconstruction and matching the application of more!)

说明：  经典高斯烟雨模型、固定点源、3d模拟、三维图、等高线图(Classic Gaussian smoke and rain model, fixed point source, 3d simulation, three-dimensional map, contour map)

四种压缩传感的重构算法，StOMP,BP,OMP,block_omp(Four kinds of compressed sensing reconstruction algorithm, StOMP, BP, OMP, block_omp)

说明：  x射线的CT图像重建，内附data.mat为实际X射线拍到投影图像。(x-ray CT image reconstruction, the actual X-ray included data.mat photographed the projected image.)
