ROI coding of volumetric medical images with application to visualisation [PDF]

open access: yes, 2003
This paper presents region of interest (ROI) coding of volumetric medical images with the region itself being three dimensional. An extension to 3D-SPIHT which allows 3D ROI coding is proposed.

Lossless compression of continuous-tone images [PDF]

open access: yesProceedings of the IEEE, 2000
In this paper, we survey some of the recent advances in lossless compression of continuous-tone images. The modeling paradigms underlying the state-of-the-art algorithms, and the principles guiding their design, are discussed in a unified manner. The algorithms are described and experimentally compared.

HYBRID COMPRESSION OF CERVICAL IMAGES BY SEGMENTING NUCLEI-CYTOPLASM [PDF]

open access: yesICTACT Journal on Image and Video Processing, 2012
A hybrid image compression method is proposed by which the Nuclei-Cytoplasm of the image is completely restorable and the background part of the image is restorable with insignificant loss.

Lossless Astronomical Image Compression and the Effects of Noise

open access: yes, 2009
We compare a variety of lossless image compression methods on a large sample of astronomical images and show how the compression ratios and speeds of the algorithms are affected by the amount of noise in the images.

Lossless compression of VLSI layout image data [PDF]

open access: yesIEEE Transactions on Image Processing, 2006
We present a novel lossless compression algorithm called Context Copy Combinatorial Code (C4), which integrates the advantages of two very disparate compression techniques: context-based modeling and Lempel-Ziv (LZ) style copying. While the algorithm can be applied to many lossless compression applications, such as document image compression, our ...

Implementation of CCSDS Standards for Lossless Multispectral and Hyperspectral Satellite Image Compression

open access: yesIEEE Transactions on Aerospace and Electronic Systems, 2020
This paper presents the modeling, design, and implementation of two intellectual property (IP) cores that are compliant with the consultative committee for space data systems (CCSDS) 121.0-B-2 and CCSDS 123.0-B-1 lossless satellite image compression ...

Lossless Compression Of Images Using Logic Minimization [PDF]

open access: yesProceedings of 3rd IEEE International Conference on Image Processing, 2002
A novel approach for the lossless compression of images is presented. After preprocessing, the image is split into bit planes which are then divided into smaller blocks. Mixed blocks are converted to Boolean switching functions and then subjected to minimization to arrive at a compact representation, leading to possible data compression.

A Reversible Data Hiding Method in Encrypted Images for Controlling Trade-Off between Hiding Capacity and Compression Efficiency

open access: yesJournal of Imaging, 2021
In this paper, we propose a new framework for reversible data hiding in encrypted images, where both the hiding capacity and lossless compression efficiency are flexibly controlled.

Practical Full Resolution Learned Lossless Image Compression

open access: yes, 2019
We propose the first practical learned lossless image compression system, L3C, and show that it outperforms the popular engineered codecs, PNG, WebP and JPEG 2000.
