如下代码，霍夫变换检测到圆并用cvcircle画出圆后，怎么输出圆心坐标?希望写出具体c++代码

才学c++和opencv，真心求教！

 (*itc)[0],(*itc)[1]

这个就是圆心坐标啊。

(*itc)[0],(*itc)[1]是point类型的，肯定不能直接cout啊，point。x point。y才能直接输出嘛

cout<<"圆心坐标x= "<<cvRound(p[0])<<endl<<"圆心坐标y= "<<cvRound(p[1])<<endl;
cout<<"半径="<<cvRound(p[2])<<endl; 这就是圆心输出语句啊

line[1], 表示什么呢？
