# Comparing pictures stored in picture_a and picture_b
# Assumes:
#  1. You've already resized the images to the same size
#  2. The width & height of the images are stored in variables of the same names
#  3. The images have been normalized to the same average intensity
#  4. You've written a function named 'intensity' to calculate the intensity of
#     a given pixel
