There are several image and speech files among the accompanying data sets.
(a) Write a program to compute the first-order entropy of some of the image and speech files.
(b) Pick one of the image files and compute its second-order entropy. Comment on the difference between the first- and second-order entropies.
(c) Compute the entropy of the differences between neighboring pixels for the image you used in part
(b). Comment on what you discover.
