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

Lossless Watermarking for Image Authentication (VC++)
IEEE Transactions on Image Processing, Vol. 15, No. 4,

Abstract:
We present a novel framework for lossless (invertible) authentication watermarking, which enables zero-distortion reconstruction of the un-watermarked images upon verification. As opposed to earlier lossless authentication methods that required reconstruction of the original image prior to validation, the new framework allows validation of the watermarked images before recovery of the original image. This reduces c ....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

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
