97) [12 points] Entropy and Huffman coding: 1. [6 points) What is the entropy of the image below (show the calculation steps)? The numbers (0, 10, 60, 80, 90) denote gray-level intensities? 10 10 60 60 90 90 0 0 0 0 0 00 0 1010 0 0 0 100 0 0 0 80 10 80 60 60 60 0 90 80 10 80 60 60 60 0 90 90 10 60 60 60 60 0 90 0 0 10 10 10 10 0 0 10 10 60 60 60 60 10 0 I 2. [6 points] Show, step-by-step, how to construct the Huffman tree to encode the above intensity values (i.e., 0, 10, 60, 80, 90) in this image. Show the resulting code for each intensity value
