چکیده

The splitting a non-binary input image into a number of lower, but not neccessarily binary, resolution subgroups is explored as a technique to improve lossless compression. The idea is to accelerate the learning in the Markov models used as part of arithmetic coders. Our technique typically improves on the \standard" JBIG method of using single (Gray coded) bit planes by approximately 4%.

Medical 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...

Implementation of VlSI Based Image Compression Approach on Reconfigurable Computing System - A Survey

Image data require huge amounts of disk space and large bandwidths for transmission. Hence, imagecompression is necessary to reduce the amount of data required to represent a digital image. Thereforean efficient technique for image compression is highly pushed to demand. Although, lots of compressiontechniques are available, but the technique which is faster, memory efficient and simple, surely...

A New Hybrid Method for Colored Image Steganography Based On DWT

Data transmission security has become an extremely important field of research. Steganography is an art of hiding information in image, audio and video files in a way that would meet the security requirements in the form of overt or covert. In this study, we propose a new hybrid steganography technique for color images that hide secret messages in the frequency domain of a cover image's blu...

Optimum decoder for multiplicative spread spectrum image watermarking with Laplacian modeling

This paper investigates the multiplicative spread spectrum watermarking method for the image. The information bit is spreaded into middle-frequency Discrete Cosine Transform (DCT) coefficients of each block of an image using a generated pseudo-random sequence. Unlike the conventional signal modeling, we suppose that both signal and noise are distributed with Laplacian distribution, because the ...

MEDICAL IMAGE COMPRESSION: A REVIEW

Within recent years the use of medical images for diagnosis purposes has become necessity. The limitation in transmission and storage space also growing size of medical images has necessitated the need for efficient method, then image Compression is required as an efficient way to reduces irrelevant and redundancy of the image data in order to be able to store or transmits data. It also reduces...
