OpenCV中DrawMatchesFlags的几种形式

#include 
#include  // 添加SURF
#include 

using namespace std;
using namespace cv;
using namespace cv::xfeatures2d; // 添加SURF相关命名空间

int main(int argc, char** argv)
{
	Mat src = imread("test.jpg", IMREAD_COLOR);
	imshow("src", src);
	int minHessian = 5000;
	Ptr detector = SURF::create(minHessian);
	vector keypoints1;
	detector->detect(src, keypoints1);
	Mat img_keypoints1;

	imshow("DrawMatchesFlags", img_keypoints1);

	waitKey(0);
	return 0;
