Several important properties of chaos synchronization with gradient based control of chaotic system with periodic parametric forcing remain still unexplored. This paper investigates the behavior of the Lorenz system to change from chaotic to periodic, parametric forcing also entrains the system output with the forcing frequency. Secondly synchronization of two identically chaotic Lorenz systems are derived by linear feedback control and then discussed the gradient based control method for Lorenz system with periodic parametric forcing. Finally numerical simulation results are presented to show the feasibility and effectiveness of the approach.

In this paper, a new nonlinear median based filtering technique is introduced for the enhancement of medical images that are highly contaminated by impulse noise. The proposed Detail Preserving Fast Median Filtering (DPFMF) technique is more effective in eliminating fixed value impulse noise and preserving the image details. The filter replaces a corrupted pixel by the median value of the fast median filter or by the value computed based on a unique criterion applied to the processed neighboring pixel values. The uncorrupted pixels are left undisturbed. Simulation studies show that the proposed filter can eliminate impulse noise of densities up to 80% while preserving the edges and fine details satisfactorily. The performance is evaluated by applying the proposed filter on different gray scale images and the superior results obtained in terms of subjective and objective evaluation are presented.

In this paper, a new 3-moduli set {2 2n+1 +2 n -1, 2 2n+1 -1, 2 n -1} with an efficient residue-to-binary converter using mixed radix conversion algorithm is presented. Moreover, by adding two redundant modulus {2 3n , 2 3n+1 -1}, a new moduli set in redundant residue number system is provided that can correct up to (2n+2) error bits. Simulation results of the error control algorithm's functionality with C++ programming language for 10'000 different error bits states show that the average percent of error detection capability using the proposed moduli set by setting n=2 is equal to 77.97%.

This paper proposes a novel preprocessing technique in order to improve the performance of a Face Recognition (FR) system. The proposed Edge-based Scale Normalization (ESN) process involves the use of scale normalization along with edge detection as a preprocessing technique in order to eliminate unwanted background details in face images. Feature extraction is performed on the preprocessed image using Discrete Fourier Transform (DFT). The DFT spectrums of these images extract the low frequency coefficients required for face recognition. These important features are selected through a rhombus-shaped mask around the center of the DFT spectrum. Further optimization in feature selection is achieved through Binary Particle Swarm Optimization (BPSO) technique. Experimental results, obtained by applying the proposed algorithm on Cambridge ORL and Extended YaleB face databases, show that the proposed system outperforms other FR systems. A significant increase in the recognition rate and a substantial reduction in the number of features is observed. Significant dimensionality reduction by more than 98.5% and improved recognition rate of 98% are achieved for both datasets. ∗Corresponding author, E-mail: kmanikantan@msrit.edu †E-mail: ramachandr@gmail.com DFT domain Feature Extraction using Edge-based Scale Normalization for Enhanced Face Recognition 135

The ongoing evolution of the Internet has enabled web applications that use real time three-dimensional (3D) graphics and virtual environments. Moreover, in recent years, cultural technology has also flourished notably. Virtual museums represent one significant application that combines culture with modern technologies and the internet, requiring an interdisciplinary approach aiming both at dissemination and education. We present our approach to enhance virtual museums by incorporating content-based retrieval that refers to 3D objects. In this context, a virtual visitor is able to navigate within the museum, examine the exhibited artifacts and perform queries-byexample in order to locate the position of related artifacts. The retrieval mechanism responds to the visitor’s queries by indicating similar artifacts, which are ranked according to their similarity scores. This way, the visitor is able to navigate within a virtual museum not only by means of a virtual walkthrough but also by means of the context.

It has already been realized by the scientific and technical community that a new form of technology is going to lead the future technological developments. This technology will be more humancentric and will be more and more “hidden” within everyday-life objects. It will be smarter, personalized, pervasive and ubiquitous. This technology includes what is called Ambient Intelligence (AmI). In this paper, we identify the main aspects of AmI through a review of the recent developments that have been achieved in these aspects of AmI and Ambient Intelligence Environments (AmIEs), as well as point out the problems yet to be solved and the visions of the future.
