CAA: Stable kernelbased approximation and applications
Kernelbased approximation have become particularly popular in the last decades
especially with the use of RBF (Radial Basis Functions). Our research is addressed
primarily to the analysis and construction of stable bases and their use
in image reconstruction from Radon data and meshless approximations.
