image processing

Assume that a gray level picture A has only 6 gray levels values:

  1. Fix the type of picture A and give the corresponding fix length code; call it Code 1
  2. Assign probabilities to those values and use Huffman coding to find their corresponding variable length code; call it Code 2
  3. What is the (average) length of Code 1?
  4. What is the average length of Code 2?
  5. Calculate the compression ratio and the relative data redundancy
