A Novel Rate Control Algorithm for Onboard Predictive Coding of Multispectral and Hyperspectral Images [PDF]

open access: yes, 2014
Predictive coding is attractive for compression onboard of spacecrafts thanks to its low computational complexity, modest memory requirements and the ability to accurately control quality on a pixel-by-pixel basis.

Lossy image compression based on prediction error and vector quantisation

open access: yesEURASIP Journal on Image and Video Processing, 2017
Lossy image compression has been gaining importance in recent years due to the enormous increase in the volume of image data employed for Internet and other applications. In a lossy compression, it is essential to ensure that the compression process does

THE EFFECT OF LOSSY IMAGE COMPRESSION ON OBJECT BASED IMAGE CLASSIFICATION – WORLDVIEW-2 CASE STUDY [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
Lossy compression is becoming increasingly used in remote sensing although its effect on the processing results has yet not been fully investigated.

On privacy amplification, lossy compression, and their duality to channel coding

open access: yes, 2018
We examine the task of privacy amplification from information-theoretic and coding-theoretic points of view. In the former, we give a one-shot characterization of the optimal rate of privacy amplification against classical adversaries in terms of the ...

Humeanism and Exceptions in the Fundamental Laws of Physics [PDF]

open access: yes, 2017
It has been argued that the fundamental laws of physics do not face a ‘problem of provisos’ equivalent to that found in other scientific disciplines (Earman, Roberts and Smith 2002) and there is only the appearance of exceptions to physical laws if they ...

Peptide‐based ligand antagonists block a Vibrio cholerae adhesin

open access: yesFEBS Letters, EarlyView.
The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

Error Resilience for Block Compressed Sensing with Multiple-Channel Transmission

open access: yesApplied Sciences, 2019
Compressed sensing is well known for its superior compression performance, in existing schemes, in lossy compression. Conventional research aims to reach a larger compression ratio at the encoder, with acceptable quality reconstructed images at the ...

Universal Sampling Rate Distortion

open access: yes, 2017
We examine the coordinated and universal rate-efficient sampling of a subset of correlated discrete memoryless sources followed by lossy compression of the sampled sources.

Lossy Compression of Unordered Rooted Trees [PDF]

open access: yes2016 Data Compression Conference (DCC), 2016
A classical compression method for trees is to exploit subtree repeats in the structure byrepresenting them by directed acyclic graphs. We propose a lossy compression method thatconsists in computing a structure with high redundancy that approximates the initial data.Trees are commonly used to represent hierarchical data appearing in computerscience or

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

open access: yesFEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...
