Reducing interpolation artifacts by globally fairing contours
Abstract
We propose an iterative fairing method for scalar fields reducing the artifacts of bi- and trilinear interpolation. Our method reconstructs a two-dimensional scalar field from interpolation constraints optimizing the smoothness of its contours (isolines) based on vari- ational principles. It generalizes to the trivariate case and is used to increase the quality of data sets employing a cubic B-spline representation. In contrast to filtering methods, our ap- proach preserves the level of detail, enhancing features supported by the data while reducing interpolation artifacts.
