Sampling Kantorovich operators for speckle noise reduction and gap filling with some applications to remote sensing
Danilo Costarelli, Mariarosaria Natale
In this paper, we investigate the application of multivariate sampling Kantorovich (SK) operators for image reconstruction, with a particular focus on gap filling and speckle noise…

Advancements in nonlinear exponential sampling: convergence, quantitative analysis and Voronovskaya-type formula
Danilo Costarelli, Mariarosaria Natale
In this paper, we introduce the nonlinear exponential Kantorovich sampling series. We establish pointwise and uniform convergence properties and a nonlinear asymptotic formula of t…
