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

A PIPELINE FAST FOURIER TRANSFORM FOR DIGITAL SPECTRUM ANALYSIS

Abstract:- This paper describes a novel structure for a hardwired fast Fourier transform (FFT) signal processor that promises to permit digital spectrum analysis to achieve throughput rates consistent with extremely wide-band radars. The technique is based on the use of serial storage for data and intermediate results and multiple arithmetic units each of which carries out a sparse Fourier transform. Details of the system are described for data sample sizes that are binary multi ....etc

INTRODUCTION
THE DISCRETE FOURIER TRANSFORM (DFT) is one of the most funtamental operations in digital signal processing. Because of the efficiency of the convolutional property, the DFT is often used in linear filtering found in many applications such as quantum mechanics, noise reduction and image re-construction. However, the computational requirements for completing the DFT of a finite length signal are relatively intensive. In particular, if the input signal has length N, directly calculating its DFT requires N 2 complex multiplications ( ....etc

Fast Fourier Transform (FFT)



Operation Count

How do we evaluate computational complexity?
count the number of real multiplications and
additions
by real we mean either fixed-point or floating point
operations depending on the specific hardware
subtraction is considered equivalent to additions
divisions are counted separately
Other operations such as loading from memory, storing in
memory, loop counting, indexing, etc are not counted
(depends on implementation/architec ....etc

Introduction
The DSP world today is ruled by different transforms. Discrete Fourier transforms are most used. So is the fast Fourier transform, which is the faster version of DFT. Suppose we take FFT of a signal. On taking the inverse fast Fourier transform, we except the output to be the same as the input. This is called the invertibility property. But on most occasions, disappointment is the result. This is due to the finite word length of the registers used to store the samples and the coefficients. This seminar introduces a method called i ....etc

DNSSEC : A Protocol towards securing

Abstract: Unlike spam, worms, viruses, and phishing all of which confront end users directly infrastructure attacks occur outside their normal frame of reference and control. But attacks on the Domain Name System (DNS), an engine of the Internet infrastructure, appear to be increasing in length and severity, affecting DNS information associated with financial services institutions, Internet service providers, and major corporations in the travel, health, technology, and media/ entertainment sectors.

Abstract
I have implemented the Fast Fourier Transform (FFT) algorithm, using the method of Cooley-Tukey. The FFT reduces the computation required in determining the Fourier Transform, which is used in several applications in science and engineering, including signal processing computations and spectral analysis. The Cooley-Tukey method primarily uses binary logic, making use of the symmetry and periodicity properties of complex exponentials. Substantial savings can be made in computation, especially when the number of input sample values is ....etc
