How do I get a Huffman code?
Huffman code is obtained from the Huffman tree. Huffman code is a = 000, b = 001, c = 010, d = 011, e = 1. This is the optimum (minimum-cost) prefix code for this distribution. Given an alphabet A with frequency distribution f(a) : a ∈ A.
Is LZW better than Huffman?
Huffman coding is well-situated than LZW coding. LZW coding facilitates more compression ratio than Huffman algorithm. Huffman coding requires more execution time than the LZW. In some cases time is not important as Huffman coding can be used to obtain high compression ratio.
Is Huffman coding the best?
Huffman coding is known to be optimal, yet its dynamic version may yield smaller compressed files. The best known bound is that the number of bits used by dynamic Huffman coding in order to encode a message of n characters is at most larger by n bits than the number of bits required by static Huffman coding.
