Explain shannon -fano algorithm, Computer Graphics

Assignment Help:

(a) Differentiate between the following compression algorithm:

1. Shannon -Fano Algorithm and
2. Huffman Encoding

(b) A statistical encoding algorithm is being considered for the transmission of a large number of long text files over a public network. Part of the file content .is as follows:

DODOCOCORICO

Using the Shannon - Fano algorithm compute the following:

i) the average number of bits per codeword

ii) the entropy of the source

iii) the minimum number of bits required assuming fixed-length codeword

iv) the compression ratio based on this algorithm if we assume an ASCII of 8 bits representation
