Opencv是一个开源的的跨平台计算机视觉库,内部实现了图像处理和计算机视觉方面的很多通用算法,对于python而言,在引用opencv库的时候需要写为import cv2。其中,cv2是opencv的C++命名空间名称,使用它来表示调用的是C++开发的opencv的接口 目前人脸识别有很多较为成熟的方法,这里调用OpenCv库,而OpenCV又提供了三种人脸识别方法...

1、OpenCV学习笔记(十二):OpenCV坐标系与row&col的关系 (Mat::at(x,y)和Mat::at(Point(x, y))的区别) row == heigh == Point.y col == width == Point.x Mat::at(Point(x, y)) == Mat::at(y,x) 2、矩形的检测, 其一般步骤是使用边缘检测出边缘,然后进行多边形逼近,使其变为只有四个点...

1 、验证 opencv 下的 dll 程序是否能够对内存起到很好的控制。方法是将图片路径写在 dll 文件中,使用 csharp 调用 dll 文件,以此来验证是否是函数内部的溢出。 DllExport void imageprocesstest1() { vector<Mat> inputmat; vector<cv::Point2f> points1; ...
