Abstract

This article presents an implementation of the chromatic aberration correction technique of Chang et al. This method decomposes aberration correction into a cascade of two 1D filters. The first one locally sharpens the red and blur edges such that they have similar profiles to that of the green channel serving a guiding image throughout restoration. The second one shifts the red and blur corrected edges to the location of the green ones to remove the color fringes. These two successive estimates are ultimately merged into a final prediction, free of most chromatic aberrations.
