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

A lossless compression method for logging data while drilling
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

COLOR IMAGE COMPRESSION BASED ON ABSOLUTE MOMENT BLOCK TRUNCATION CODING USING DELTA ENCODING AND HUFFMAN CODING [PDF]
A simple and easy to implement technique for improving absolute moment block truncation coding (AMBTC) is proposed. AMBTC method produce a fixed length binary representation of each block according to the block size of the image.

On the Randomness of Compressed Data
It seems reasonable to expect from a good compression method that its output should not be further compressible, because it should behave essentially like random data.

Implementation of Clock Gating for Power Optimizing in Synchronous Design
Huffman coding is very important technique in information theory. Compression technique is the technology for reducing the amount of data used to denote any content without decreasing the quality.

Lossless Text Image Compression using Two Dimensional Run Length Encoding
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.
