# Importing an Image
# ==================

# imshow takes 2 arguments, the first is the name of the window, and the second is the name of the img
# img = cv2.imread("Resources/lena.png")
# cv2.imshow("Output",  img)
# cv2.waitKey(0)

# ==================
# Importing a Video
# ==================

# cap = cv2.VideoCapture("Resources/test_video.mp4")

# Since a video is a sequence of Images, hence we need a while loop to iterate over all the frames of the video
# while True:

#     cv2.imshow("Video", img)
#     if cv2.waitKey(1) & 0xFF == ord('q'):
#         break
