An Efficient Architecture for 2-D Lifting-basedDiscrete Wavelet Transform
I. INTRODUCTION
The two-dimensional discrete wavelet transform (2-DWT) is widely used in many image compression techniques,and adopted to be an ingredient in many image compression standards, such as JPEG2000,
The computation transform has been widely
implemented in very-large-scale integration (VLSI) to meetreal time requirement.
In this paper, an efficient line-based VLSI architecture for 2-D DWT using lifting scheme is p ....etc

HIGH CAPACITY AND SECURITY STEGANOGRAPHY USING
DISCRETE WAVELET TRANSFORM



Abstract

The secure data transmission over internet is achieved using Steganography. In
this paper High Capacity and Security Steganography using Discrete wavelet
transform (HCSSD) is proposed. The wavelet coefficients of both the cover and
payload are fused into single image using embedding strength parameters alpha
and beta. The cover and payload are preprocessed to reduce the pixel range to
ensure the payload is recovered a ....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

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

Discrete Wavelet Transform (DWT)
Overview
Need for Compression
Transmission and storage of uncompressed video would be extremely costly and impractical.
Frame with 352x288 contains 202,752 bytes of information
Recoding of uncompressed version of this video at 15 frames per second would require 3 MB. One minute180 MB storage. One 24-hour day262 GB
Using compression, 15 frames/second for 24 hour1.4 GB, 187 days of video could be stored using the same disk space that unc ....etc

Abstract
This paper presents an efficient implementation of a convolution-based 1D discrete wavelet transform (DWT). The proposed architecture combines several optimizations that improve the performance of the hardware design in terms of throughput and power dissipation. We designed and analyzed the performance of numerous DWT architectures using pertinent metrics and cost functions that assess the impact of the design optimizations. We synthesized our VLSI architectures using a 0.18μ standard cell library. The final VLSI design combi ....etc
