INTRODUCTION:
Def: The main problem is that this “great idea requires too many bits. In fact there exist many coding techniques that will effectively reduce the total number of bits needed to represent the above information. In this lossless data compression algorithms we perform that compression of the data, and also it involves that no distortion of the original signal once it is decompressed or reconstituted. So much da ....etc

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 ....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 ....etc

Abstract”

Fourphase codes have been widely used in radar and communication areas, but the synthesis of Four phase codes with good merit factor is a nonlinear multivariable optimization problem, which is usually difficult to tackle. To get the solution of above problem many global optimization algorithms like genetic algorithm, simulated annealing, and tunneling algorithm were reported in the literature. However, there is no guarantee to get global optimum point. In this paper, a novel and efficient VLSI architectu ....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

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 ....etc
