Compute the mean squared value of coefficients

Question

Response to the following problem:

Let us compare the energy compaction properties of the DCT and the DWHT transforms.

(a) For the Sena image, compute the mean squared value of each of the 64 coefficients using the DCT. Plot these values.

(b) For the Sena image, compute the mean squared value of each of the 64 coefficients using the DWHT. Plot these values.

(c) Compare the results of (a) and (b). Which transform provides more energy compaction? Justify your answer.
