Weighting of double exponential distributed data in lossless image compression

, 1998
A probability assignment technique for weighting-based double exponential data in lossless image compression is introduced. It is shown that this technique has a favorable effect on compression when compared with traditional estimation ...

JPEG and BPG visually lossless image compression via KonJND-1k database

Vojnotehnički Glasnik
Introduction/purpose: This paper presents the results of the research on visually lossless image compression which is of particular interest because it achieves a high degree of compression, while the visual quality of the image is not impaired, i.e ...

Lossless medical image compression through lightweight binary arithmetic coding

, 2017
A contextual lightweight arithmetic coder is proposed for lossless compression of medical imagery. Context definition uses causal data from previous symbols coded, an inexpensive yet efficient approach.

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

, 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 high-volume numerical data from simulations

, 2000
Summary form only given. We propose a lossless algorithm of delta compression (a variant of predictive coding) that attempts to predict the next point from previous points using higher-order polynomial extrapolation. In contrast to traditional predictive

Lossless Microarray Image Compression by Hardware Array Compactor

Iranian Journal of Electrical and Electronic Engineering, 2005
Microarray technology is a new and powerful tool for concurrent monitoring of large number of genes expressions. Each microarray experiment produces hundreds of images. Each digital image requires a large storage space.
