Testing out ssim between 2 images, then visualise the difference. Using scikit-image

SSIMExample.py

from skimage.metrics import structural_similarity as ssim
import cv2
import matplotlib.pyplot as plt

imgGold = cv2.imread("C:/Users/aobon_ktnb1ku/Documents/SSIM Test/Screenshot_1.png", 0)
imgTest = cv2.imread("C:/Users/aobon_ktnb1ku/Documents/SSIM Test/Screenshot_2.png", 0)

ssimScore, diff = ssim(imgGold, imgTest, full=True)

# diff here is image array
diff = (diff * 255).astype("uint8")

print (ssimScore)

plt.imshow(diff, cmap='jet')
plt.colorbar()
plt.show()
