A Two-Stage Scheme for Lossless Compression of Images
نویسندگان
چکیده
A two-stage lossless image compression scheme is presented , the rst stage of which decorrelates the raw image data by using a two-dimensional, causal linear predic-tor, resulting in signiicant entropy reduction. The second stage uses standard coding techniques. Diierent two-stage schemes are compared with respect to their performances on several images, using bilevel coding, arithmetic coding, and adaptive Huuman coding.

Lossless Microarray Image Compression by Hardware Array Compactor
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. Hence, real-time processing of these images and transmission of them necessitates efficient and custom-made lossless compression schemes. In this paper, we offer a new archi...

Compression can be done by lossy or lossless methods. The lossy methods have been used more widely than the lossless compression. Although, many methods for image compression have been proposed yet, the methods using intelligent skipping proper to the visual models has not been considered in the literature. Image inpainting refers to the application of sophisticated algorithms to replace lost o...
متن کاملTsip - Efficient Lossless Compression of Colour Image Data with Diverse Characteristics
Lossless compression of data is the attempt to model the data in such a manner that the resulting file contains the pure information without any redundancy. This paper presents an universal compression system, which is able to efficiently compress images with a broad range of characteristics from natural images to synthetic images with sparse histograms. The proposed compression scheme uses a n...
متن کاملGrayscale true two-dimensional dictionary-based image compression
Dictionary-based encoding methods are popular forms of data compression. These methods were initially implemented to reduce the one-dimensional correlation in data, since they are designed to compress text. Therefore, they do not take advantage of the fact that adjacent pixels in images are correlated in two dimensions. Previous attempts have been made to adapt dictionary-based compression sche...
متن کاملMedical Image Compression Based on Region of Interest
Medical images show a great interest since it is needed in various medical applications. In order to decrease the size of medical images which are needed to be transmitted in a faster way; Region of Interest (ROI) and hybrid lossless compression techniques are applied on medical images to be compressed without losing important data. In this paper, a proposed model will be presented and assessed...
