WebHuffman Coding Compression Algorithm. Huffman coding (also known as Huffman Encoding) is an algorithm for doing data compression, and it forms the basic idea behind file compression. This post talks about the fixed-length and variable-length encoding, uniquely decodable codes, prefix rules, and Huffman Tree construction. The output from Huffman's algorithm can be viewed as a variable-length codetable for encoding a source symbol (such as a character in a file). The algorithm derives this table from the estimated probability or frequency of occurrence (weight) for each possible value of the source symbol. Meer weergeven In computer science and information theory, a Huffman code is a particular type of optimal prefix code that is commonly used for lossless data compression. The process of finding or using such a code proceeds by … Meer weergeven In 1951, David A. Huffman and his MIT information theory classmates were given the choice of a term paper or a final exam.

ASCII is 8-bit character coding scheme. But it is defined only for 0-127 codes which means it can be fit into 7-bits. The leftmost bit of an ASCII coded character is always set to zero i.e. the MSB is guaranteed to be 0. We’ve taken advantage of that bit.
