OpenCV提供了函数Canny()实现Canny算子,其原型如下: 代码语言:javascript 复制 voidCanny(InputArray image,OutputArray edges,double threshold1,double threshold2,int apertureSize=3,bool L2gradient=false) Image—输入图像,要求是数据深度为8bit的图像,官方文档中并没有说输入图像必须为单通道,但很多资料上都说要求...
按照上面的步骤一步步实现基于Canny的边缘检测算法,代码如下: 代码语言:javascript 复制 constdoublePI=3.1415926;doublegetSum(Mat src){double sum=0;for(int i=0;i<src.rows;i++){for(int j=0;j<src.cols;j++){sum+=(double)src.at<double>(i,j);}}returnsum;}MatCannyEdgeDetection(cv::Mat src...
