1. Import the Computer Vision package - cv2:

import cv2 

2. Read the image using the built-in imread function:

image = cv2.imread('image_2.jpg')

3. Display the original image using the built-in imshow function:

cv2.imshow("Original", image) 

4. Wait until any key is pressed:

cv2.waitKey(0) 

5. Perform the required operation on the test image:

# cv2.flip is used to flip images 
# Horizontal flipping of images using value '1' 
flipping = cv2.flip(image, 1) 

6. Display the horizontally flipped image:

# Display horizontally flipped image 
cv2.imshow("Horizontal Flipping", flipping) 

7. Wait until any key is pressed:

cv2.waitKey(0) 

8. Perform vertical flipping of input image:

# Vertical flipping of images using value '0' flipping = cv2.flip(image, ...
