Variable-to-Variable Huffman Coding: Optimal and Greedy Approaches [PDF]

open access: yesEntropy, 2022
In this paper, we address the problem of m-gram entropy variable-to-variable coding, extending the classical Huffman algorithm to the case of coding m-element (i.e., m-grams) sequences of symbols taken from the stream of input data for m>1.

Single-trial extraction of event-related potentials (ERPs) and classification of visual stimuli by ensemble use of discrete wavelet transform with Huffman coding and machine learning techniques [PDF]

open access: yesJournal of NeuroEngineering and Rehabilitation, 2023
Background Presentation of visual stimuli can induce changes in EEG signals that are typically detectable by averaging together data from multiple trials for individual participant analysis as well as for groups or conditions analysis of multiple ...

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

Efficient coding of information: Huffman coding [PDF]

open access: yesResonance, 2018
In his classic paper of 1948, Claude Shannon considered the problem of efficiently describing a source that outputs a sequence of symbols, each associated with a probability of occurrence, and provided the theoretical limits of achievable performance. In

A Data Compression Method for Wellbore Stability Monitoring Based on Deep Autoencoder [PDF]

open access: yesSensors
The compression method for wellbore trajectory data is crucial for monitoring wellbore stability. However, classical methods like methods based on Huffman coding, compressed sensing, and Differential Pulse Code Modulation (DPCM) suffer from low real-time

An efficient chain code with Huffman coding

open access: yesPattern 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.
