I've tried to google this to no avail. Please help me understand what is wrong with this file path:

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

I've tried changing:

  • backslash to double backslash
  • backslash to forward slash backslash
  • to double forward slash

Thank you for your assistance

change ALL occurences of \to either \\ or / (not only the last)

(it's not even an opencv specific problem, you'll have to do this, whenever you encounter a file path in c++ on win)

Thank you for your time. I tried double backslash or forward and double forward slashes to no avail.
