Introduction

Wavelet transforms have been one of the important signal processing developments in the last decade, especially for the applications such as time-frequency analysis, data compression, segmentation and vision. During the past decade, several efficient implementations of wavelet transforms have been derived. The theory of wavelets has roots in quantum mechanics and the theory of functions though a unifying framework is a recent occurrence. Wavelet analysis is performed using a prototype function called a wavelet.

Wavelets are ....etc

Wavelet Video Processing Technology

Uncompressed multimedia data requires considerable storage capacity and transmission bandwidth. Despite rapid progress in mass storage density processor speeds and digital communication system performance, demand for data storage capacity and data transmission bandwidth continues to outstrip the capabilities of available technologies. The recent growth of data intensive multimedia-based web applications have not only sustained the need for more efficient ways to ....etc

ABSTRACT

This paper presents a new design and implementation of HDD (Hard Disk Drive) embedded DSR (Digital Satellite Receiver). The digital broadcasting technology enables multimedia access via broadcasting system. The amount of digital data to be processed is increased as compared to the previous broadcasting environment. In this paperâ„¢ a method is proposed to provide storage ability of a DSR to cope with these changes. Efficient digital data storage and management technology is also discussed. The real data recording and playing b ....etc

The biggest obstacle to the multimedia revolution is digital obesity. This is the blot that occurs when pictures, sound and video are converted from their natural analog form into computer language for manipulation or transmission. In the present explosion of high quality data, the need to compress it with less distortion of data is the need of the hour. Compression lowers the cost of storage and transmission by packing data into a smaller space. One of the hottest areas of advanced form of compression is wavelet compression. Wavelet Video ....etc

Abstract
Synthetic Aperture Radar (SAR) image compression is important in image transmission and archiving. In this paper, SAR image compression using embedded zerotree wavelets algorithm, based on discrete wavelet transform (DWT), is researched. Aiming at special characteristics of SAR image such as speckle noise, the author added a denoise step in the flow of compression, trying to do some meaningful attempt in SAR image compression. Experiments carried out show that the improvement can reduce the speckle noise and improve the compu ....etc
