5. Differentiate between regional descriptors and boundary descriptors.
6. What do you understand by object/patterns? What is the need of object/pattern
recognition?
7. Perform the Huffman coding
Symbol I1 I2 I3 I4 I5 I6
P(rk) 0.5 0.1 0.05 0.05 0.2 0.1
Find the entropy and maximum efficiency.
8. Briefly explain the following operations:
i) Dilation
ii) Erosion
iii) Opening
iv) Closing
9. Calculate the efficiency of Huffman code for the following symbol whose probability
of occurrence is given below :
Symbol I1 I2 I3 I4
P(rk) 0.9 0.06 0.02 0.02
