Abstract

Contourlets form a multiresolution directional tight frame designed to efficiently approximate images made of smooth regions separated by smooth boundaries. The Contourlet transform has a fast implementation based on a Laplacian Pyramid decomposition followed by directional filterbanks applied on each bandpass subband. ....etc

wavelet based contourlet transform and its application to image coding ppt

In this paper, we first propose a new family of geometrical image transforms that decompose images both radially and angularly. Our construction comprises two stages of filter banks that are non-redundant and perfect reconstruction and therefore lead to an overall non-redundant and perfect reconstruction transform. Using the wavelet transform as the first stage, we apply directional filter banks to the wavelet coefficients in such a way to maintain the anisotropy scali ....etc

Introduction


Steganography is the art and science of writing secret data in such a way that no one, except the sender and intended recipient, knows of the existence of the data. The information-hiding process in a steganographic system starts by identifying a cover medium s redundant bits those that can be modified without destroying that medium s integrity. The embedding process creates a stego medium by replacing these redundant bits with data from the hidden message. The cover medium can be text, image, audio, video, and multim ....etc
