Spatial autoregressive (AR) models have been extensively used to represent texture images in machine learning applications. This work emphasizes the contribution of 2D autoregressive models for analysis and synthesis of textural images. Autoregressive model parameters as a feature set of texture image represent texture and used for synthesis. Yule walker Least Square (LS) method has used for parameter...
Secured data transmission over computer networks can be achieved through steganography. In specific, Image Steganography entails the opportunity of hide any secret information into images. This paper presents the implementation of two image steganographic techniques in MATLAB. The first is a filter method to embed text information into image and new methods have been demonstrated to increase the information...
