cv2.imread frame code example

Example 1: cv2 load image

import numpy as np
    import cv2
    import matplotlib.pyplot as plt
    %matplotlib inline # if you are running this code in jupyter notebook

    img = cv2.imread('/path_to_image/opencv-logo.png',0) # reads image 'opencv-logo.png' as grayscale
    plt.imshow(img, cmap='gray')

Example 2: cv2.imread cannot load image

//There is no such code to fix this problem.
//Usually cv2.imread(path) does not load image when the path is invalid.
//Make sure your path is correct and try again :)
