Approximating scattered data with discontinuities
The aim of this paper is to present a method for approximating scattered data by a function defined on a regular two-dimensional grid. The method requires three phases: regularization, local approximation, and extrapolation. Two examples from seismic data are presented. The method is interesting for other areas: computer aided design, terrain modelling in the mapping, industrial shape estimations in molecular modelling, and modelling of geological surfaces in oil reservoir engineering.
