Lossy Infrared Image Compression Based on Wavelet Coefficient Probability Modeling and Run-Length-Enhanced Huffman Coding [PDF]

open access: yesSensors
Infrared line-scanning images have high redundancy and large file sizes. In JPEG2000 compression, the MQ arithmetic encoder’s complexity slows down processing. Huffman coding can achieve O(1) complexity based on a code table, but its integer-bit encoding

On the application of wavelet transform and Huffman algorithm to Yorùbá language syntax text files compression [PDF]

open access: yesSerbian Journal of Electrical Engineering, 2022
Most algorithms of data compression were developed with English language as target text syntax. However, this paper approaches the problem of Yorùbá text files compression via the use of Discrete Wavelet Transform (DWT) and Huffman algorithm ...

A lossless compression method for logging data while drilling

open access: yesSystems Science & Control Engineering, 2021
Mud pulse transmission technology is widely used in logging while drilling (LWD), while its low data transmission efficiency has restricted the development of LWD technology for a long time. In order to improve the equivalent data transmission efficiency

A Decentralized Medical Network for Maintaining Patient Records Using Blockchain Technology

open access: yesCybernetics and Information Technologies, 2022
Personal Medical Records (PMR) manage an individual’s medical information in digital form and allow patients to view their medical information and doctors to diagnose diseases. Today’s institution-dependent centralized storage, fails to give trustworthy,

Average Redundancy for Known Sources: Ubiquitous Trees in Source Coding [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
Analytic information theory aims at studying problems of information theory using analytic techniques of computer science and combinatorics. Following Hadamard's precept, these problems are tackled by complex analysis methods such as generating functions,

Existence, Uniqueness, and Optimality of Sibling-Property Codes for Infinite Sources [PDF]

open access: yes, 2006
By definition Huffman codes only exist for finite sources, since the Huffman algorithm cannot be applied to an infinite source. On the other hand, Gallager's sibling property, which was introduced as a characterization of Huffman codes, extends naturally

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.
