A Low-Complexity Lossless Compression Method Based on a Code Table for Infrared Images
Applied SciencesTraditional JPEG series image compression algorithms have limitations in speed. To improve the storage and transmission of 14-bit/pixel images acquired by infrared line-scan detectors, a novel method is introduced for achieving high-speed and highly ...

Optimal Prefix Free Codes with Partial Sorting
Algorithms, 2019 We describe an algorithm computing an optimal prefix free code for n unsorted positive weights in time within O ( n ( 1 + lg α ) ) ⊆ O ( n lg n ) , where the alternation α ∈ [ 1 . .

Huffman codes and self-information [PDF]
IEEE Transactions on Information Theory, 1976 In this paper the connection between the self-information of a source letter from a finite alphabet and its code-word length in a Huffman code is investigated. Consider the set of all independent finite alphabet sources which contain a source letter a of probability p .

An efficient chain code with Huffman coding
Pattern Recognition, 2005 This paper presents a new chain code based on the eight-direction Freeman code. Each element in the chain is coded as a relative angle difference between it and the previous element. Statistical analysis showed that the probabilities of the Freeman codes differ importantly. Therefore, the Huffman coding was applied.
