Activity 1.01: Mirror Effect with a Twist

Solution:

1. Let's start by importing the necessary libraries:

   # Load modules

   import cv2

   import numpy as np

   import matplotlib.pyplot as plt

2. Next, let's specify the magic command for displaying images in a notebook:

   %matplotlib inline

3. Now, we can load the image and display it using Matplotlib.

   Note

   Before proceeding, ensure that you can change the path to the images (highlighted) based on where the image is saved in your system.

   The code is as follows:

   # Load image

   img = cv2.imread("../data/lion.jpg")

   plt.imshow(img[:,:,::-1])

   plt.show()

   The output is as follows:
