可以实现图像篡改检测，附带有几张图片，检测效果一般(Image tamper detection can be achieved, with pictures, the detection effect is general)

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

PLY文件的读取和写入程序：PLY文件是一个三维图形的数据存储格式，包括了三维曲面上所有采样点的坐标，以及所有采样点间的网络拓扑(A program which can read and write a PLY file)

主要是实现图像的融合,是在梯度域里面进行一个图像的融合，(shi xian tu xiang de rong he，in tidu yulimian rong he ercheng ,matlab huan jing,xia ,keyi yunxing qieyou ceshi shuju d e.)

本资源给出了用matlab画各种三维图的源代码，非常齐全。(The resorce provides the resorce programs of drawing 3D maps using matlab.)

通过使用MATLAB语言建立三维渐开线齿轮啮合模型(use MATLAB to draw 3-D gear)

说明：  在MTLAB环境运行main_msbcsspl.m。该程序的功能是实现图像的稀疏分解并重建图像，采用压缩感知理论，利用小波分析，在小波域分块观测，可以用很少的观测值就能重建原图像。程序包中已经整合了小波包和测试图像，没有多余文件，程序经过亲测并修改，能在MATLAB中直接运行得到很好的结果，速度非常快！(Run main_msbcsspl.m in the MTLAB environment. The function of the program is to decompose and reconstruct the image sparsely. Using compressed sensing theory and wavelet analysis, the original image can be reconstructed with very few observations. Wavelet package and test image have been integrated in the package. There are no redundant files. After testing and modifying the program, it can run directly in MATLAB and get good results. The speed is very fast.)

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.)

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)

在P4P问题中,当空间4个点共面时,不仅摄像机坐标系与物体坐标系之间 的旋转矩阵R和平移向量t可以线性求解,而且可以同时确定摄像机的有效焦距f和像素比例，该程序设计模拟已知相机矩阵M情况下由已知三维空间点和图像坐标情况求解相机外参数矩阵(When space four points coplanar P4P problem, not only between the camera coordinate system and the object coordinate system rotation matrix R and translation vector t Can be solved linearly, and can determine the camera s effective focal length f and pixel ratio, the program is designed to simulate a known camera matrix M Camera outside the parameters matrix case solved by the known three-dimensional space points and image coordinates)
