Digital images are often used in several domains. Large amount of data is necessary to
represent the digital images so the transmission and storage of such images are time …

Image compression is the methodology of reducing the data space required to store an
image or video. It finds great application in transferring videos and images over the web to …

Compression for color image is now necessary for transmission and storage in the data
bases since the color gives a pleasing nature and natural for any object, so three composite …

In this paper a novel image compression technique based on EZW (Embedded Zero Tree
Wavelet Coding) algorithm is presented. EZW algorithm encodes the image to compress it …

Image compression processes moderate the number of bits essential to signify an image,
which can improve the performance of systems during storage and transmission without …

The contemporary period of information technology facilitates simple duplication,
manipulation and distribution of digital data. This enduringly, has insisted the rightful …

Finding orthogonal matrices in different sizes is very complex and important because it can
be used in different applications like image processing and communications (eg CDMA and …

This paper focuses on comparison of different wavelet coders such as SPIHT, SPECK, BISK
and TARP for efficient storage and better transmission. Set partition methods like SPIHT …

We describee some possible options for implementation of the Discrete multiwavelet
transform (DMWT) of an image by using filter banks. DMWT can be implemented by two …

Video coding schemes for low bit-rate is of high importance and traditional coding schemes
which use block transforms suffer from blocking artefacts. Here we propose a Video Codec …
