matlab code for edge preservation index of an image

A common technique for removing noise from images is by blur-
ring them with a weighted mean or a Gaussian filter. Through these
processes noise reduction is achieved, but unfortunately, valuable
information is lost and the details of object boundaries are
deformed. A solution to this problem, especially for document
images, is the use of an edge preserving smoothing technique
(adaptive mean filter) where the amount of blurring for each pixel is
determined after gathering local informa ....etc

hi,this is kavitha im doing a project on edge adaptive image steganography based on lsb matching revisited,im having abstract and requirements ,i need source code for my project
ABSTRACT :

The least-significant-bit (LSB)-based approach is a popular type of steganographic algorithms in the spatial domain. However, we find that in most existing approaches, the choice of embedding positions within a cover image mainly depends on a pseudorandom number generator without considering the relationship between the image content itself and the si ....etc

edge histogram descriptor using matlab code

This is the last kind of histograms I used in my project. The basic idea is to build a histogram with the directions of the gradients of the edges (borders or contours). It is possible to detect edges in an image but it in this we are interest in the detection of the angles. This is possible trough Sobel operators. The next five operators could give an idea of the strength of the gradient in five particular directions .

The convolution against each of this mask produce a matrix of the same size of t ....etc

Steganography (US Listeni/ st . n . r .fi/, UK / st . n .r .fi/) is the practice of concealing a file, message, image, or video within another file, message, image, or video. The word steganography combines the Greek words steganos ( ), meaning covered, concealed, or protected, and graphein ( ) meaning writing.

The first recorded use of the term was in 1499 by Johannes Trithemius in his Steganographia, a treatise on cryptography and steganography, disguised as a book on magic. Generally, the hidden messages appear to be (or ....etc

Abstract

Modern information hiding technology is an important branch of information security. Hiding capacity is very much important for efficient covert communication. The redundancies of digital media as well as the characteristic of human visual system make hiding technology a significant one. Steganography is the Art and Science of writing hidden messages in such a way that no one, apart from the sender and intended recipient suspects the existence of the message. Images are the mostly cover objects used for information hiding schemes. Ima ....etc

EDGE Compact and EDGE Classic Packet Data Performance
Abstract
Even though cellular radio services have been extremely successful in providing untethered voice communications, wireless data services have captured only a limited market share so far. One obstacle for wireless data services is their limited peak bit rates. Existing wireless data rates, up to several tens of kb/s, may be over one order of magnitude short of what is required to make popular applications user-friendly. To accomplish these necessities we go for ....etc
