Archiving and Distribution of 2-D Geophysical Data Using Image Formats With Lossless Compression
Abstract
Certain types of two-dimensional (2-D) numerical remote sensing data can be losslessly and compactly compressed for archiving and distribution using standardized image formats. One common method for archiving and distributing data involves compressing data files using file compression utilities such as gzip and bzip2, which are widely available on UNIX and Linux operating systems. GZIP-compressed files and bzip2-compressed f ....etc

A Pseudo Lossless Image Compression Method
I. INTRODUCTION
Data compression methods can be reversible (error-free) or irreversible (lossy).
A reversible scheme can only achieve a aximum compression ratio of about 2.5, but will allow exact recovery of the original image from the compressed version.
This compression ratio is limited by the noise in the image which degrades the correlation between pixels.
I. INTRODUCTION(cont.)
Today, lossy compression methods are not being used by radiologists in primary di ....etc

This article describes a efficient hardware architecture for Lempel-Ziv-Welch (LZW) data compression algorithm. The encoding and decoding operations are done simultaneously using a CAM array. In order to to achieve search and twofold store operations in single access during regular match operations, an anhanced CAM architecture is also proposed. the implementation of the LZW algorithm is accelerated by these enhanced CAM cells. the proposed
design is evaluated using the Corpus benchmarks.

Abstract
We present an adaptive lossless video compression algorithm based on predictive coding. The proposed algorithm exploits temporal, spatial, and spectral redundancies in a backward adaptive fashion with extremely low side information. The computational complexity is further reduced by using a caching strategy. We also study the relationship between the operational domain for the coder (wavelet or spatial) and the amount of temporal and spatial redundancy in the sequence being encoded. Experimental results show that the proposed s ....etc

An Improved Lossless Image Compression Algorithm Loco-R

International Conference On Computer Design And Applications (Iccda )- Image Processing Java

This paper presents a state-of-the-art implementation of lossless image compression algorithm LOCO-R, which is based on the LOCO-I (low complexity lossless compression for images) algorithm developed by weinberger, Seroussi and Sapiro, with modifications and betterment, the algorithm reduces obviously the implementation complexity. Experiments illustrate that this algorithm is better than ....etc
