Abstract


With the increase in the availability of digital data such as multimedia services on the Internet, there is a pressing need to manage and protect the illegal duplications a, solution to this problem, a digital watermark technology is now drawing the attentions a new method of protecting copyrights for digital data. In this paper, we present two methods of digital watermark for image signals based on the wavelet transform. We classify wavelet coefficients as insignificant or significant by using zero tree which is defined in the e ....etc

Video Watermarking using Integer-to-Integer Discrete Wavelet Transform (Java)
Proceedings on Digital Watermarking, TENCON

Abstract:
This paper proposes a novel video watermarking technique to embed a digital watermark in video data using integer-to-integer discrete wavelet transform. The watermark is embedded in the lowest frequency components of each frame. The method exploits features of the human visual system. The watermark can be extracted directly from the decoded video without access to the original video. Experimental resul ....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

Image Steganography Technique Based on Wavelet Transform
In the technique of steganography, information is concealed in unremarkable cover media so as not to arouse an eavesdropper’s suspicion. It is widely used in the field of information security. The strengths and counter measures are
driven by weaknesses and vulnerabilities. There are easy to use communication channels for steganography. In this article, a modified high-capacity image steganography technique that depends on wavelet transform is described which has acceptable le ....etc

Discrete Wavelet Transform-Based Satellite Image Resolution Enhancement




INTRODUCTION

RESOLUTION of an image has been always an important
issue in many image- and video-processing applications,
such as video resolution enhancement , feature extraction
, and satellite image resolution enhancement .
Interpolation in image processing is a method to increase
the number of pixels in a digital image. Interpolation has been
widely used in many image ....etc
