cout << "mat2=" << endl << mat2 << endl << endl;

Mat mat3 = Mat::ones(3,3,CV_8UC1);//全1矩阵

cout << "mat3=" << endl << mat3 << endl << endl;

Mat mat4 = Mat::zeros(3,3,CV_32F);//全0矩阵

cout << "mat4=" << endl << mat4 << endl << endl;

Point2f p2(6.5,2.1);//2维点

cout << "p2=" << endl << p2 << endl << endl;

Point3i p3(6,2,3);//3维点

cout << "p3=" << endl << p3 << endl << endl;

waitKey();
