Image data compression [PDF]

open access: yesJournal of Digital Imaging, 1997
The tutorial will expand on all of the topics outlined above and will provide additional information on other compression techniques. The practical implications of data compression and the important considerations in choosing a compression scheme will also be discussed.

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,

Transform Network Architectures for Deep Learning Based End-to-End Image/Video Coding in Subsampled Color Spaces

open access: yesIEEE Open Journal of Signal Processing, 2021
Most of the existing deep learning based end-to-end image/video coding (DLEC) architectures are designed for non-subsampled RGB color format. However, in order to achieve a superior coding performance, many state-of-the-art block-based compression ...

Interactive Compression of Digital Data

open access: yesAlgorithms, 2010
If we can use previous knowledge of the source (or the knowledge of a source that is correlated to the one we want to compress) to exploit the compression process then we can have significant gains in compression.

Improved Single Breath-Hold SSFSE Sequence for Liver MRI Based on Compressed Sensing: Evaluation of Image Quality Compared with Conventional T2-Weighted Sequences

open access: yesDiagnostics, 2022
The purpose of this study was to evaluate the image quality of compressed-sensing accelerated single-shot fast spin-echo (SSFSECS) sequences acquired within a single breath-hold in comparison with conventional SSFSE (SSFSECONV) and multishot TSE (mTSE ...

Deep learning for in situ data compression of large turbulent flow simulations

open access: yes, 2020
Large turbulent flow simulations can lead to information bottlenecks as data is generated faster than it can be processed and saved. Innovative in-situ data compression techniques are needed.

Information-Theoretic Method for Assessing the Quality of Translations

open access: yesEntropy, 2022
In recent years, the task of translating from one language to another has attracted wide attention from researchers due to numerous practical uses, ranging from the translation of various texts and speeches, including the so-called “machine” translation,

Massive optimal data compression and density estimation for scalable, likelihood-free inference in cosmology [PDF]

open access: yes, 2018
Many statistical models in cosmology can be simulated forwards but have intractable likelihood functions. Likelihood-free inference methods allow us to perform Bayesian inference from these models using only forward simulations, free from any likelihood ...
