A novel semi-blind defocused image deconvolution technique is proposed, which is based on multivariate local polynomial regression and iterative Wiener filtering. In this technique, firstly a multivariate local polynomial regression model is trained in wavelet domain to estimate defocus parameter. After obtaining the point spread function (PSF ) parameter, iterative wiener filter is adopted to ...

The purpose of this paper is to introduce the concept of general fuzzy multivalued variational inclusions and to study the existence problem and the iterative approximation problem for certain fuzzy multivalued variational inclusions in Banach spaces. Using the resolvent operator technique and a new analytic technique, some existence theorems and iterative approximation techniques are presented...

This paper presents an iterative algorithm for approximating gray-scale images with adaptive triangular meshes ensuring a given tolerance. At each iteration, the algorithm applies a non-iterative adaptive meshing technique. In this way, this technique converges faster than traditional mesh refinement algorithms. The performance of the proposed technique is studied in terms of compression ratio ...

In this paper, we use the new decomposition technique to suggest and analyze new iterative methods for solving nonlinear equations. Our technique of developing these iterative methods is very simple as compared with other techniques. We prove the eighth order convergence of the proposed method. Various numerical examples are given to illustrate the performance of the new method.

This paper presents an iterative technique for the transient analysis of large structurally unrestricted semi-Markov processes (SMPs), which builds on our previous work on iterative passage time calculation. The method is based on the calculation and subsequent numerical inversion of Laplace transforms. We demonstrate our technique on a Markovian process algebra model of a web-server with 69 44...

We survey the conceptual framework and several applications of the iterative compression technique introduced in 2004 by Reed, Smith, and Vetta. This technique has proven very useful for achieving a number of recent breakthroughs in the development of fixed-parameter algorithms for NP-hard minimization problems. There is a clear potential for further applications as well as a further developmen...

We present iterative decoding process of Geometric Augmented Product codes that is a newly proposed linear block code construction technique. We also report the bit error performances for one of the constructed code of the technique utilising our iterative decoding approach.

In this paper, we extend a monotone iterative technique for nonlocal fractional differential equations with finite delay in an ordered Banach space. By using the monotone iterative technique, theory of fractional calculus, semigroup theory and measure of noncompactness, we study the existence and uniqueness of extremal mild solutions. An example is presented to illustrate the main result.

the aim of this paper is to introduce a new approach for obtaining the numerical solution of singulary perturbed boundary value problems based on an optimal control technique. in the proposed method, first the mentioned equations are converted to an optimal control problem. then, control and state variables are approximated by chebychev series. therefore, the optimal control problem is reduced ...
