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

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

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

ABSTRACT
Transforms that maps integers to integers have advantagesnot available for floating point transforms. Integercomputations are faster and free from round off errors(integer transforms are widely used for lossless coding). Thepaper presents an algorithm of Integer Fast FourierTransform (intFFT) based on lifting factorization. IntegerDiscrete Cosine Transform (intDCT) is also computed as anexample of intFFT application.
1. INTRODUCTION
Great interest in the topic of integer transforms can beobserved in literature during ....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
