Lossless Text Image Compression using Two Dimensional Run Length Encoding

open access: yesJOIN: Jurnal Online Informatika, 2020
Text images are used in many types of conventional data communication where texts are not directly represented by digital character such as ASCII but represented by an image, for instance facsimile file or scanned documents.

A Lossless Compression Method for Chat Messages Based on Huffman Coding and Dynamic Programming

open access: yesComputers, 2021
There is always an increasing demand for data storage and transfer; therefore, data compression will always be a fundamental need. In this article, we propose a lossless data compression method focused on a particular kind of data, namely, chat messages,

Huffman coding

open access: yesInternational journal of health sciences, 2022
In the proposed Huffman LEACH model, energy consumption increases exponentially with distance and there are no maximum limits. The transmit power level of a sensor node can only be adjusted to discrete values that may result in one transmit power level for various distances.

Asymmetrical Two-Level Scalar Quantizer with Extended Huffman Coding for Compression of Laplacian Source

open access: yesAdvances in Electrical and Computer Engineering, 2013
This paper proposes a novel model of the two-level scalar quantizer with extended Huffman coding. It is designed for the average bit rate to approach the source entropy as close as possible provided that the signal to quantization noise ratio (SQNR ...

An Efficient Encoding Algorithm Using Local Path on Huffman Encoding Algorithm for Compression

open access: yesApplied Sciences, 2019
Huffman encoding and arithmetic coding algorithms have shown great potential in the field of image compression. These algorithms are the origin of current image compression techniques. Nevertheless, there are some deficiencies in both algorithms that use

Prefix Codes: Equiprobable Words, Unequal Letter Costs [PDF]

open access: yes, 1996
Describes a near-linear-time algorithm for a variant of Huffman coding, in which the letters may have non-uniform lengths (as in Morse code), but with the restriction that each word to be encoded has equal probability.
