初识Opencv4.X----像素最值寻找

	Mat img = Mat(2, 5, CV_32FC1,a);
	double min_value, max_value;
	Point min_local, max_local;
	cout << img << endl;
	minMaxLoc(img, &min_value, &max_value, &min_local, &max_local);
	cout << "最大像素值：" << max_value << max_local << endl;
	cout << "最小像素值：" << min_value << min_local << endl;
	//当图像为多通道时，可以通过reshape函数变为单通道
	return 0;
