Performance comparison of Huffman Coding and Double Huffman Coding
2016 Sixth International Conference on Innovative Computing Technology (INTECH), 2016Huffman coding [11] is a most popular technique for generating prefix-free codes [7, 10]. It is an efficient algorithm in the field of source coding. It produces the lowest possible number of code symbols of a single source symbol [1]. Huffman coding is a most widely used lossless compression technique [2].

Summary: We examine the problem of deciphering a file that has been Huffman coded, but not otherwise encrypted. We find that a Huffman code can be surprisingly difficult to cryptanalyze. We present a detailed analysis of the situation for a three-symbol source alphabet and present some results for general finite alphabets.

Huffman’s algorithm for computing minimum-redundancy prefix-free codes has almost legendary status in the computing disciplines. Its elegant blend of simplicity and applicability has made it a favorite example in algorithms courses, and as a result it is perhaps one of the most commonly implemented algorithmic techniques.

This note shows how to maintain a prefix code that remains optimum as the weights change. A Huffman tree with nonnegative integer weights can be represented in such a way that any weight w at level l can be increased or decreased by unity in O(l) steps, preserving minimality of the weighted path length.

Purpose – David Huffman, as a graduate student, earned his immortality by solving a problem that had stumped Claude Shannon, the creator of the field of information theory. How he saw the problem differently and the nature of his discovery have implications for how we get stuck, how we get unstuck, and how the internal ...

Weighted Adaptive Huffman Coding
2020 Data Compression Conference (DCC), 2020Huffman coding is known to be optimal in case the alphabet is known in advance, the set of codewords is fixed and each codeword consists of an integral number of bits. If one of these conditions is violated, optimality is not guaranteed. In the dynamic variant of Huffman coding the encoder and decoder maintain identical copies of the model; at each ...
