# Python program to explain cv2.imshow() method

# importing cv2
import cv2

path = r'Pictures/robert.jpg'

# Reading an image in default mode
image = cv2.imread(path)

# Window name in which image is displayed
window_name = 'image'

# Using cv2.imshow() method
# Displaying the image
cv2.imshow(window_name, image)

#waits for user to press any key
#(this is necessary to avoid Python kernel form crashing)
cv2.waitKey(0)

#closing all open windows
cv2.destroyAllWindows()
