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

Lossy Compression with Near-uniform Encoder Outputs
, 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
, 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
, 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
, 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
Information 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.

Learning Better Lossless Compression Using Lossy Compression [PDF]
2020 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR), 2020 We leverage the powerful lossy image compression algorithm BPG to build a lossless image compression system. Specifically, the original image is first decomposed into the lossy reconstruction obtained after compressing it with BPG and the corresponding residual.

Medically Relevant Criteria used in EEG Compression for Improved Post-Compression Seizure Detection
, 2014 Biomedical signals aid in the diagnosis of different disorders and abnormalities. When targeting lossy compression of such signals, the medically relevant information that lies within the data should maintain its accuracy and thus its reliability.
