Abstract:
AbstractIn the present paper, an inverse result of approximation, i.e. a saturation theorem for the sampling Kantorovich operators, is derived in the case of uniform approximation for uniformly continuous and bounded functions on the whole real line. In particular, we prove that the best possible order of approximation that can be achieved by the above sampling series is the order one, otherwise the function being approximated turns out to be a constant. The above result is proved by exploiting a suitable representation formula which relates the sampling Kantorovich series with the well-known generalized sampling operators introduced by Butzer. At the end, some other applications of such representation formulas are presented, together with a discussion concerning the kernels of the above operators for which such an inverse result occurs.

Abstract:
Abstract In this paper we establish a variation-diminishing type estimate for the multivariate Kantorovich sampling operators with respect to the concept of multidimensional variation introduced by Tonelli. A sharper estimate can be achieved when step functions with compact support (digital images) are considered. Several examples of kernels have been presented.

Abstract:
In this thesis new methods concerning the application of sampling Kantorovich operators to real world problems are proposed and their results are revised. In particular, after a theoretical introduction, problems connected with: segmentation of thermal bridges, spatial localizazion of acoustic bridges, individuation of pervious lumen of aorta vessel by computed tomography images without contrast medium, improvement of OCTA retinal vessels image quality, are investigated.
