说明：  lsb数字水印算法，SB算法利用了数字图像处理中位平面的原理,即改变图像的最低位的信息,对图像信息产生的影响非常小,人眼的视觉感知系统往往不能察觉。以一幅256灰度的图像为例, 256 灰度共需要8 个位来表示,但其中每一个位的作用是不一样的,越高位对图像的影响越大,反之越低的位影响越小,甚至不能感知。(Digital watermarking algorithm based on lsb)

说明：  图片的加法运算减法运算乘法运算除法运算和四则运算(Four Operations of Addition, Subtraction, Multiplication and Multiplication of Pictures)

基于多阈值的图像分割()

一个用IDL编写的GUI视图工具 详细源代码与工程文件 包含加载影像 RGB波段合成列表选择 放缩与全图漫游 鹰眼图 矢量数据空间叠加等视图处理功能 按照说明书操作即可！(IDL prepared using a GUI tool to view a detailed source code and project file contains the load image list to select RGB-Band Synthetic zoom map with roaming space Hawkeye map overlay vector data such as view processing functions can be operated in accordance with the Manual!)

点云三维重建中需要用的法向量计算，能够有效避免法向量不一致的问题，更好进行三维重建。测试有用。(Normal vector calculation point cloud reconstruction in need, and can effectively avoid the problem of inconsistent normals, better three-dimensional reconstruction. Useful for testing.)

摄像机标定程序，实现单目，双目摄像机的标定(calibration of camera )

说明：  机器视觉中三维重建的源码 具体包括4个文件，其中.c文件用于产生图像特征点矩阵(In the three-dimensional reconstruction process, resulting in the source image feature dot matrix)

Iris数据集，计算协方差矩阵和相关系数矩阵和kl变换(The goal of this programming experiment is to: Calculate the covariance matrix and the correlation coefficient matrix of the Iris data set. Perform the Karhunen-Loeve transform on this data set.)
