\ is used for an escape sequence.

Instead, use the below lines of code:

Mat lena = imread("C:\\Users\\dasboomer\\Desktop\\Building-Computer-Vision-Projects-with-OpenCV4-and-CPlusPlus-master\\Chapter03\\lena.jpg");

or

Mat lena = imread("C:/Users/dasboomer/Desktop/Building-Computer-Vision-Projects-with-OpenCV4-and-CPlusPlus-master/Chapter03/lena.jpg");

You are correct, it turns out the tutorial code was faulty. My my, where has packt gone? – Das Boomer Jul 26 '20 at 18:03
Hi Rahul! Yes. For some reason, the code that follows was flagging it as not loaded. // Create windows namedWindow("Lena", WINDOW_NORMAL); // Checking if Lena image has been loaded if (!lena.data) { cout << "Lena image missing!" << endl; return -1; } – Das Boomer Jul 26 '20 at 20:26
