Huffman Codec and Its Fast Algorithm

Xiaofei Li

Abstract

Huffman coding is a good variable-length prefix code,invented by D.A.Huffman in 1952.Huffman coding as an efficient and simple variable-length coding has been widely used in areas such as source coding.The basic Huffman coding algorithm is introduced,and for its shortcomings,dynamic Huffman coding algorithm is introduced,improved algorithm to encode the data is based on dynamic changes of the Huffman tree.
