Fast Chromatic Aberration Correction with 1D Filters,
Image Processing On Line, 13 (2023), pp. 198–214.

This article presents an implementation of the chromatic aberration 
correction technique of Chang et al. [Correction of Axial and Lateral 
Chromatic Aberration with False Color Filtering, IEEE Transactions on 
Image Processing, 2013]. This method decomposes aberration correction 
into a cascade of two 1D filters. The first one locally sharpens the red 
and blue edges such that they have similar profiles to that of the green 
channel serving as guiding image throughout restoration. The second one 
shifts the red and blue 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
