Global Smoothness Preservation and Uniform Convergence of Singular Integral Operators in the Fuzzy Sense

2011
In this chapter, we study the fuzzy global smoothness and fuzzy uniform convergence of fuzzy Picard, Gauss- Weierstrass and Poisson- Cauchy singular fuzzy integral operators to the fuzzy unit operator. These are given with rates involving the fuzzy modulus of continuity of a fuzzy derivative of the involved function.

A novel signal reconstruction method with sharp feature preservation

International Conference on Applied Mathematics, Modelling and Intelligent Computing, 2023
Aiming at the fact that traditional signal reconstruction method based on traditional methods such as Fourier and wavelets transformations cannot preserve the sharp features in the original data well, a signal reconstruction method is proposed in this ...

A curve fitting method for sharp feature preservation

Computer Technology and Information Science, 2022
To address the fact that the traditional curve fitting method based on B-spline basis functions cannot preserve the sharp features in the original data well, a curve fitting method based on a class of orthogonal piecewise polynomial function Vsystem is ...

A Global Laplacian Smoothing Approach with Feature Preservation

Ninth International Conference on Computer Aided Design and Computer Graphics (CAD-CG'05), 2006
This paper presents a novel approach for surface smoothing with feature preservation on arbitrary meshes. Laplacian operator is performed in a global way over the mesh. The surface smoothing is formulated as a quadratic optimization problem, which is easily solved a sparse linear system.

Non‐linear prestack seismic inversion with global optimization using an edge‐preserving smoothing filter

Geophysical Prospecting, 2013
ABSTRACTEstimating elastic parameters from prestack seismic data remains a subject of interest for the exploration and development of hydrocarbon reservoirs. In geophysical inverse problems, data and models are in general non‐linearly related. Linearized inversion methods often have the disadvantage of strong dependence on the initial model.
