图像的基本元素是像素。在opencv中能够直接对cv::Mat类型的图像调用at函数读取或赋值某个像素//在一张图像上增加椒盐噪声，image为输入图像。n为噪点个数void salt(Mat &image, int n){for(int k = 0;k < n;k++){//随机产生白色噪点int i = qrand()%image.cols;int j = qr...

薄透镜薄透镜公式针孔相机模型在薄透镜公式的基础上，提出以下假设1 摄像机的孔径无穷小（针孔，只考虑光心处的射线）2 物距远大于像距（图像位于焦距处）3 把图像放在相机前方（正立的图像，数学上可行）...

原因分析：把引用的windows的头文件注释掉就不报红线了问题的原因是std::min/max与windows中min/max的宏定义产生了冲突。解决办法：注释windows头文件是一种解决方案；或者使用预处理器来屏蔽min/max：项目属性 ——> C/C++ ——> 预处理器 ——> 预处理器定义 ——>加入NOMINMAX作者：JoannaJuanCV...
