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

ppt for discrete wavelet transform based satellite image resolution enhancemnet

Satellite images are being used in many fields of research. One of the major issues of these types of images is their resolution. In this paper, we propose a new satellite image resolution enhancement technique based on the interpolation of the high-frequency subbands obtained by discrete wavelet transform (DWT) and the input image. The proposed resolution enhancement technique uses DWT to decompose the input image into different subbands. Then, the high-frequency ....etc

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

Today, as the digitization develops day by day, the protection
of digital information becomes an urgent problem.
In order to resist different kinds of infringement, a new
technology that called watermarking had been put forward
to in the international scope. Watermark is sequence
carrying information about the copyright owner
to embed into the digital image , audios and videos in
order that owners can read it out while unauthorized users
cannot1 easily remove it.
There are many methods to embed the watermark. It
can be divided into ....etc
