Getting error for mouse setback

Hi, I am trying to use mouse callback function to crop out the rectangular area by clicking twice on the image. Below is code and error message.

include "opencv2/opencv.hpp"

using namespace std; using namespace cv;

vector<point>pt; Mat RectifiedImage; int main() { Mat RectifiedImage= imread("image.png"); imshow("Rectified Image", RectifiedImage); setMouseCallback("Rectified Image", onMouse, &pt); Mat ROI; while (true) { if (pt.size() <= 2) { int x = pt[0].x; int y = pt[0].y; int x1 = pt[1].x; int y1 = pt[1].y; ROI = RectifiedImage(Rect(x, y, x1 - x, y1 - y)); return false; }

    }

    imshow("left video stream", ROI);

static void onMouse(int event, int i, int j, int flags, void* param) { Mat &RectifiedImage = ((Mat)param); Point p; if (event == EVENT_LBUTTONDOWN) { p = { i,j }; pt.push_back(p); cout << i << j << endl; }
} waitKey(0); return 0; }
