Lossy compression of permutations [PDF]

open access: yes2014 IEEE International Symposium on Information Theory, 2014
We investigate the lossy compression of permutations by analyzing the trade-off between the size of a source code and the distortion with respect to Kendall tau distance, Spearman’s footrule, Chebyshev distance and `1 distance of inversion vectors.

A New Algorithm for the On-Board Compression of Hyperspectral Images

open access: yesRemote Sensing, 2018
Hyperspectral sensors are able to provide information that is useful for many different applications. However, the huge amounts of data collected by these sensors are not exempt of drawbacks, especially in remote sensing environments where the ...

Hiding Data Using Efficient Combination of RSA Cryptography, and Compression Steganography Techniques

open access: yesIEEE Access, 2021
Data compression is an important part of information security because compressed data is more secure and easy to handle. Effective data compression technology creates efficient, secure, and easy-to-connect data.

Lossy Compression with Near-uniform Encoder Outputs

open access: yes, 2016
It is well known that lossless compression of a discrete memoryless source with near-uniform encoder output is possible at a rate above its entropy if and only if the encoder is randomized.

A statistical-mechanical view on source coding: physical compression and data compression

open access: yes, 2010
We draw a certain analogy between the classical information-theoretic problem of lossy data compression (source coding) of memoryless information sources and the statistical mechanical behavior of a certain model of a chain of connected particles (e.g ...

Statistical mechanics of lossy data compression using a non-monotonic perceptron

open access: yes, 2002
The performance of a lossy data compression scheme for uniformly biased Boolean messages is investigated via methods of statistical mechanics. Inspired by a formal similarity to the storage capacity problem in the research of neural networks, we utilize ...

Data Compression in the Petascale Astronomy Era: a GERLUMPH case study

open access: yes, 2015
As the volume of data grows, astronomers are increasingly faced with choices on what data to keep -- and what to throw away. Recent work evaluating the JPEG2000 (ISO/IEC 15444) standards as a future data format standard in astronomy has shown promising ...

Lossy compression of general random variables

open access: yesInformation and Inference: A Journal of the IMA, 2023
AbstractThis paper is concerned with the lossy compression of general random variables, specifically with rate-distortion theory and quantization of random variables taking values in general measurable spaces such as, e.g. manifolds and fractal sets. Manifold structures are prevalent in data science, e.g.

Unlocking the potential of digital pathology: Novel baselines for compression

open access: yesJournal of Pathology Informatics
Digital pathology offers a groundbreaking opportunity to transform clinical practice in histopathological image analysis, yet faces a significant hurdle: the substantial file sizes of pathological whole slide images (WSIs).
