A modified approach to data hiding in Microsoft Word documents by change-tracking technique
Journal of King Saud University: Computer and Information Sciences, 2020 Steganography is a hidden way of communication, where one person communicates with the other by using some medium under the garb of a cover, without any suspicion created on the part of any unauthorized intermediary about the existence of the secret ...

Space-efficient Huffman codes revisited
Information Processing Letters, 2023 Canonical Huffman code is an optimal prefix-free compression code whose codewords enumerated in the lexicographical order form a list of binary words in non-decreasing lengths. Gagie et al. (2015) gave a representation of this coding capable to encode or decode a symbol in constant worst case time. It uses $σ\lg \ell_{\text{max}} + o(σ) + O(\ell_{\text{

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 .

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 ...
