Shape preserving approximation properties to family of α-Bernstein shifted knot operators

Journal of Inequalities and Applications
The main idea of this paper is to obtain approximation results by utilizing the shifted knots properties of the family of α-Bernstein operators. We examine some basic results and estimate the moments of this new family of α-Bernstein operators. We derive

Perceptually motivated shape evolution with shape-preserving property [PDF]

Pattern Recognition Letters, 2008
In this paper we introduce a novel concept of shape evolution. It is perceptually motivated and takes the local shape symmetry into account. In particular, during the new shape evolution the shape parts in accordance with the human perception are removed step by step and the coarse parts remain geometrically unchanged during removing the fine parts ...

Shape Preserving Properties for q-Bernstein-Stancu Operators

Journal of Mathematics, 2014
We investigate shape preserving for q-Bernstein-Stancu polynomials Bnq,α(f;x) introduced by Nowak in 2009. When α=0, Bnq,α(f;x) reduces to the well-known q-Bernstein polynomials introduced by Phillips in 1997; when q=1, Bnq,α(f;x) reduces to Bernstein ...

Shape preserving properties of univariate Lototsky–Bernstein operators

Journal of Approximation Theory, 2017
The main goal of the present paper is to study shape preserving properties of univariate Lototsky-Bernstein operators, which are based on Lototsky-Bernstein basis functions. The Lototsky-Bernstein basis functions \(b_{n,k} (x)\) (\(0 \leq k\leq n\)) of order \(n\) are constructed by replacing \(x\) in the \(i\)th factor of the generating function for ...

Shape preserving properties of generalized Bernstein operators on Extended Chebyshev spaces [PDF]

Numerische Mathematik, 2009
We study the existence and shape preserving properties of a generalized Bernstein operator $B_{n}$ fixing a strictly positive function $f_{0}$, and a second function $f_{1}$ such that $f_{1}/f_{0}$ is strictly increasing, within the framework of extended Chebyshev spaces $U_{n}$. The first main result gives an inductive criterion for existence: suppose

Shape-Preservation of the Four-Point Ternary Interpolating Non-stationary Subdivision Scheme

Frontiers in Physics, 2020
In this paper, we present the shape-preserving properties of the four-point ternary non-stationary interpolating subdivision scheme (the four-point scheme). This scheme involves a tension parameter.
