#include <opencv2/imgcodecs.hpp> 
#include <opencv2/highgui.hpp> 
#include <opencv2/imgproc.hpp> 
#include <iostream> 

using namespace cv; 
using namespace std; 
///////////////// Images ////////////////////// 


int main() {

    string path = "H:\Wallpaper"; 
    Mat img = imread(path); 
    imshow("Image", img); 
    waitKey(0);
    return 0; 
}

please check img.empty() after imread()
(your path looks invalid/not an image)

also, 1st time noob uses a file path, right ?
NEVER use a single \. it must be either \\ or /
