How can I visualize changes in images using Python?

You can use libraries like Matplotlib and OpenCV to visualize changes in images. Would you like a code example?

Yes, please provide a code example for comparing two images.

Sure! Here's a simple example using OpenCV:

import cv2
import matplotlib.pyplot as plt

# Load the two images
image1 = cv2.imread('image1.jpg')
image2 = cv2.imread('image2.jpg')

# Compute the absolute difference
difference = cv2.absdiff(image1, image2)

# Display the images
plt.subplot(1, 3, 1)
plt.imshow(cv2.cvtColor(image1, cv2.COLOR_BGR2RGB))
plt.title('Image 1')

plt.subplot(1, 3, 2)
plt.imshow(cv2.cvtColor(image2, cv2.COLOR_BGR2RGB))
plt.title('Image 2')

plt.subplot(1, 3, 3)
plt.imshow(cv2.cvtColor(difference, cv2.COLOR_BGR2RGB))
plt.title('Difference')

plt.show()

What if I want to highlight the differences instead of just showing them?

You can use thresholding to highlight the differences. After computing the absolute difference, apply a threshold to create a binary image that highlights the changes.
