Near-Lossless Image Compression: Minimum-Entropy, Constrained-Error Dpcm

open access: yes, 1995
A near-lossless image compression scheme is presented. It is essentially a DPCM system with a mechanism incorporated to minimize the entropy of the quantized prediction error sequence.

NEAR-LOSSLESS AND SCALABLE COMPRESSION FOR MEDICAL IMAGING USING A NEW ADAPTIVE HIERARCHICAL ORIENTED PREDICTION

open access: yes, 2010
International audienceA new adaptive approach for lossless and near-lossless scalable compression of medical images is presented. It combines the adaptivity of DPCM schemes with hierarchical oriented prediction (HOP) in order to provide resolution ...

Performance optimisation of a lossless compression algorithm using the PACE toolkit [PDF]

open access: yes
With the large increase in interest and research in distributed systems, the need for performance prediction and modelling of such systems has become important to decrease the system's complexity.

AE-DD: Autoencoder-Driven Dictionary with Matching Pursuit for Joint ECG Denoising, Compression, and Morphology Decomposition

open access: yesAI
Background: Electrocardiogram (ECG) signals are crucial for cardiovascular diagnosis, but their analysis face challenges from noise contamination, compression difficulties due to their non-stationary nature, and the inherent complexity of its ...

Fast Near-Lossless or Lossless Compression of Large 3D Neuro-Anatomical Images

open access: yes, 2004
3D neuro-anatomical images and other volumetric data sets are important in many scientific and biomedical fields. Since such sets may be extremely large, a scalable compression method is critical to store, process and transmit them.

Lossless compression of multispectral images using spectral information

open access: yes, 2009
Multispectral images are available for different purposes due to developments in spectral imaging systems. The sizes of multispectral images are enormous. Thus transmission and storage of these volumes of data require huge time and memory resources. That

Lossless and near lossless compression of pharynx and esophagus in fluoroscopy medical images

open access: yes, 2015
Hospitals and medical centres produce an increasing amount of digital medical data for health examinations. Fluoroscopy is one of imaging modalities that is produced daily and generates an enormous amount of data over time, requiring a large storage ...

Lossless Compression of Multispectral Images Using Prediction and Golomb Rice Coding

open access: yes, 2009
Lossless compression algorithms of multispectral images are typically divided into two stages, a decorrelation stage and a coding stage. This work deals with the design of predictors for the decorrelation stage which are both fast and good.

Integrated Lossy, Near-lossless, and Lossless Compression of Medical Volumetric Data

open access: yes, 2008
We propose an integrated, wavelet based, two-stage coding scheme for lossy, near-lossless and lossless compression of medical volumetric data. The method presented determines the bit-rate while encoding for the lossy layer and without any iteration.
