چکیده
In network applications communication is the main aspect in present days. Data transformation is the process of sending data from one person to another person. In this contrast present security is the main issue in network communication. Steganography is the one of the data hiding technique that can be used in secret data sharing applications. Traditionally Forbidden Zone Data Hiding was developed in data security mechanism. By using framework present in the forbidden zone data hiding we developed different data hiding processes for video Steganography. Secured erasure cryptography techniques were developed in data sharing between every movement for text extraction. But in this technique customer interaction is less for network communication and data hiding process with security. So, in this paper we propose to extend Forbidden Zone Data Hiding technique with Human Visual System. Human Visual System is used by video processing expert to deal with biological and psychological processes that are not fully understood. Our experimental results show efficient data security based on Human Visual System based on spatial temporally adaption of data hiding methods.

This paper investigates digital data hiding schemes. The concept of information hiding will be explained at first, and its traits, requirements, and applications will be described subsequently. In order to design a digital data hiding system, one should first become familiar with the concepts and criteria of information hiding. Having knowledge about the host signal, which may be audio, image, ...
متن کاملDetermination of Spatial-Temporal Correlation Structure of Troposphere Ozone Data in Tehran City
Spatial-temporal modeling of air pollutants, ground-level ozone concentrations in particular, has attracted recent attention because by using spatial-temporal modeling, can analyze, interpolate or predict ozone levels at any location. In this paper we consider daily averages of troposphere ozone over Tehran city. For eliminating the trend of data, a dynamic linear model is used, then some featu...

ABSTRACT Background: The brain response to temporal frequencies (TF) has been already reported, but with no study reported for different TF with respect to various spatial frequencies (SF). Materials and Methods: fMRI was performed by 1.5T GE-system in 14 volunteers during checkerboard, with TFs of 4, 6, 8 and 10Hz in low and high SFs of 0.5 and 8cpd. Results: Average percentage BOLD signa...

Introduction: The accuracy of analyzing Functional MRI (fMRI) data is usually decreases in the presence of noise and artifact sources. A common solution in for analyzing fMRI data having high noise is to use suitable preprocessing methods with the aim of data denoising. Some effects of preprocessing methods on the parametric methods such as general linear model (GLM) have previously been evalua...
متن کاملSpatial-Temporal Trend Modeling for Ozone Concentration in Tehran City
Fitting a suitable covariance function for the correlation structure of spatial-temporal data requires de-trending the data. In this article, some potential models for spatial-temporal trend are presented. Eventually the best model will be announced for de-trending tropospheric ozone concentration data for the city of Tehran (Capital city of Iran). By using the selected trend model, some ...
