from skimage import data, exposure
import matplotlib.pyplot as plt

camera = data.camera()
camera_equalized = exposure.equalize_hist(camera)

plt.figure(figsize=(7, 3))

plt.subplot(121)
plt.imshow(camera, cmap='gray', interpolation='nearest')
plt.axis('off')
plt.subplot(122)
plt.imshow(camera_equalized, cmap='gray', interpolation='nearest')
plt.axis('off')
plt.tight_layout()
