We present a new image scaling method both for downscaling and upscaling, running with
any scale factor or desired size. The resized image is achieved by sampling a bivariate …

The paper deals with de la Vallée Poussin type interpolation on the square at tensor product
Chebyshev zeros of the first kind. The approximation is studied in the space of locally …

In order to solve Prandtl-type equations we propose a collocation-quadrature method based
on de la Vallée Poussin (briefly VP) filtered interpolation at Chebyshev nodes. Uniform …

The paper deals with a special filtered approximation method, which originates interpolation
polynomials at Chebyshev zeros by using de la Vallée Poussin filters. In order to get an …

The present paper concerns filtered de la Vall\'ee Poussin (VP) interpolation at the
Chebyshev nodes of the four kinds. This approximation model is interesting for applications …

The paper deals with the numerical solution of Cauchy Singular Integral Equations based on
some non standard polynomial quasi–projection of de la Vallée Poussin type. Such kind of …

A product quadrature rule, based on the filtered de la Vallée Poussin polynomial
approximation, is proposed for evaluating the finite weighted Hilbert transform in [− 1, 1] …

The paper concerns the weighted uniform approximation of a real function on the d-cube-1,
1^ d, with d> 1, by means of some multivariate filtered polynomials. These polynomials have …

A product quadrature rule, based on the filtered de la Vall\'ee Poussin polynomial
approximation, is proposed for evaluating the finite Hilbert transform in [-1; 1]. Convergence …

This paper is the continuation of a previous work where the authors have introduced a new
class of quadrature rules for evaluating the finite Hilbert transform. Such rules are product …
