import scipy.misc

from scipy import ndimage

import matplotlib.pyplot as plt



face = scipy.misc.face(gray=True)

blurred_face = ndimage.gaussian_filter(face, sigma=3)

local_mean = ndimage.uniform_filter(face, size=11)



plt.figure(figsize=(9, 3))

plt.subplot(131)

plt.imshow(blurred_face, cmap=plt.cm.gray)

plt.axis('off')

plt.subplot(132)

plt.imshow(very_blurred, cmap=plt.cm.gray)

plt.axis('off')

plt.subplot(133)

plt.imshow(local_mean, cmap=plt.cm.gray)

plt.axis('off')



plt.subplots_adjust(wspace=0, hspace=0., top=0.99, bottom=0.01,

                    left=0.01, right=0.99)



plt.show()
