Characterization of Stochastic Properties of Embedded Message and the Lsb Pattern in Colour and Gray-scale Images

چکیده
LSB steganography is one of the popular ways of message embedding in different multimedia cover objects. A number of commercial steganography software tools use LSB insertion as a method of message packing. In the present work the detailed study has been made regarding the stochastic properties of the embedded message and LSB pattern in colour and gray scale images. The influence of the initial noise already existing within the LSB pattern of the cover image on the embedded bit stream has been studied experimentally. A higher order statistic based method has been proposed to eliminate the initial noise level to estimate the extracted bit stream length robustly.

Evaluation of gray scale changes of CBCT system images in different axis using the DICOM file
The images of dental CBCT imaging systems used in conic shaped beams, stored in the DICOM format, have various applications in the dentistry, including bone density estimation to select the location of the orthodontic implant, bone loss detection and etc. In these systems, unlike CT imaging systems, the resulting images exhibit gray-scale non-uniformity in each of the different axis in FOV. Thi...

Assessment of pavement distresses is one of the important parts of pavement management systems to adopt the most effective road maintenance strategy. In the last decade, extensive studies have been done to develop automated systems for pavement distress processing based on machine vision techniques. One of the most important structural components of computer vision is the feature extraction met...
متن کاملAn Implementation of LSB Steganography Using DWT Technique
Steganography is the art or practice of concealing a message, image, or file within another message, image, or file. In steganography, there is a technique in which the least significant bit is modified to hide the secret message, known as the least significant bit (LSB) steganography. Least significant bit matching images are still not well detected, especially, at low embedding rate. In this ...

This paper devotes itself to the study of secret message delivery using cover image and introduces a novel steganographic technique based on genetic algorithm to find a near-optimum structure for the pair-wise least-significant-bit (LSB) matching scheme. A survey of the related literatures shows that the LSB matching method developed by Mielikainen, employs a binary function to reduce the numbe...
متن کاملSteganalysis Method for LSB Replacement Based on Local Gradient of Image Histogram
In this paper we present a new accurate steganalysis method for the LSBreplacement steganography. The suggested method is based on the changes that occur in thehistogram of an image after the embedding of data. Every pair of neighboring bins of ahistogram are either inter-related or unrelated depending on whether embedding of a bit ofdata in the image could affect both bins or not. We show that...
