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

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

ABSTRACT
Mathematical transformations are applied to signals to obtain further information from the signal that is not readily available in the raw signal. By applying the various transformations available today, the frequency information in these signals is obtained. There are many transforms that are used quite often by engineers and mathematicianâ„¢s. Hilbert transforms, short-time Fourier transforms, Radon transform, and the Wavelet transform constitute only a small portion of a huge list of transf ....etc

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

A FAST PIPELINED IMPLEMENTATION OF TWO DIMENSIONAL INVERSE DISCRETE COSINE TRANSFORMS

Abstract:- The inverse discrete cosine transform (IDCT) is a significant component in todayâ„¢s JPEG and MPEG decoders. Of all the stages in the decoding process of a JPEG file, the IDCT is the most computationally intensive. Hence, we require fast and efficient implementations, either in software or hardware. Numerous individual designs for computing the ID-IDCT have been proposed. Our 2D-IDCT incorporates two of our ID-IDCT cores and a transpose netwo ....etc
