In this section, we will try to develop the code for reading and displaying an image using C++ and OpenCV. The entire code for this is as follows it is then explained line by line:
#include <opencv2/opencv.hpp>#include <iostream>using namespace cv;using namespace std;int main(int argc, char** argv){ // Read the image Mat img = imread("images/cameraman.tif",0); // Check for failure in reading an Image if (img.empty()) { cout << "Could not open an image" << endl; return -1; } //Name of the window String win_name = "My First Opencv Program"; // Create a window namedWindow(win_name); // Show our image inside the created window. imshow(win_name, img); // Wait for any keystroke in the window waitKey(0);
