Polar Lattices for Lossy Compression [PDF]

open access: yesIEEE Transactions on Information Theory, 2021
Polar lattices, which are constructed from polar codes, have recently been proved to be able to achieve the capacity of the additive white Gaussian noise (AWGN) channel. In this work, we propose a new construction of polar lattices to solve the dual problem, i.e., achieving the rate-distortion bound of a memoryless Gaussian source, which means that ...

Lossy compression of Earth system model data based on a hierarchical tensor with Adaptive-HGFDR (v1.0) [PDF]

open access: yesGeoscientific Model Development, 2021
Lossy compression has been applied to the data compression of large-scale Earth system model data (ESMD) due to its advantages of a high compression ratio.

Lossy Compression With Universal Distortion

open access: yesIEEE Transactions on Information Theory, 2022
We consider a novel variant of $d$-semifaithful lossy coding in which the distortion measure is revealed only to the encoder and only at run-time, as well as an extension of it in which the distortion constraint $d$ is also revealed at run-time. Two forms of rate redundancy are used to analyze the performance, and achievability results of both a ...

Performance analysis of compression algorithms for information security: A Review [PDF]

open access: yesEAI Endorsed Transactions on Scalable Information Systems, 2020
Data compression is a vital part of information security, since compressed data is much more secure and convenient tohandle. Effective data compression technique creates an effective, secure, easy communicable & redundant data.

Effect of Lossy JPEG Compression of an Image with Chromatic Aberrations on Target Measurement Accuracy [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014
This paper reports an experiment conducted to investigate the effect of lossy JPEG compression of an image with chromatic aberrations on the measurement accuracy of target center by the intensity-weighted centroid method.
