ABSTRACT
Wavelet-based image coders like the JPEG2000 standard
are the state of the art in image compression. Unlike traditional
image coders, however, their performance depends
to a large degree on the choice of a good wavelet. Most
wavelet-based ....etc

Abstract
The biometric person authentication technique based on the pattern of the human iris is well suited for application to any access control system requiring a high level of security. Iris technology has been applied to person verification and identification. This thesis examines
1) Comparitive study of biometric security techniques such as fingerprint, voice, facial, retina and iris.
2) An algorit ....etc

Display of 1D continuous wavelets





Complex Morlet wavelet
Here we take the complex Morlet wavelet as a plane wave modulated by a Gaussian envelope.

where the parameter k0 is the wavenumber associated with the Morlet wavelet, roughly
corresponding to the number of oscillations of the wavelet.
The Fourier transform of the complex Morlet wavelet is

As one can see, this is not zero ....etc

INVESTIGATION OF ECG SIGNAL USING DSP PROCESSOR AND WAVELETS

The analysis of the ECG has been widely used for diagnosing many cardiac
diseases. The ECG is a graphic record of the direction and magnitude of the electrical
activity that is generated by depolarization and repolarization of the atria and
ventricles. One cardiac cycle in an ECG signal consists of the P-QRS-T waves. Most of
the clinically useful information in the ECG is found in the intervals and amplitudes
defined by i ....etc

ABSTRACT

This project presents a novel voice verification system using wavelet transforms. The conventional signal processing techniques assume the signal to be stationary and are ineffective in recognizing non stationary signals such as the voice signals. Voice signals which are more dynamic could be analyzed with far better accuracy us ....etc

HIGH CAPACITY,LOSSLESS,SECURE IMAGE STEGANOGRAPHY USING WAVELETS




IMAGE STEGANOGRAPHY

Steganography means – “COVERED WRITING”.

It’s a concealed communication

Image steganography is the technique hiding a payload (message) is hided
inside cover image (carrier),to get a stego-image.

Cover image is not statistically changed.

The modern example of steganography is a microdot.


DRAWBACKS….

COMPOUND WAVELETS: WAVELETS FOR SPEECH RECOGNITION



INTRODUCTION
The wavelet transform has become a popular tool for
image and speech processing, pitch
detection and speech recognition in previous work


The wavelet transform (WT) has the best features of narrow
band and wide band analysis within one transform.
The WT of a speech signal produces fine time resolution
at high frequencies and fine frequency resolu ....etc
