load image with openCV Mat c++

Question

I want to load an image using Mat in openCV

My code is:

Mat I = imread(\"C:/images/apple.jpg\", 0);
namedWindow( \"Display window\", CV_WINDOW_AUTOSI         


        

Answer 1

Have you checked that I exists after imread? Perhaps the file read failed

After reading a file do if ( I.empty() ) to check if it failed
