Cliff Reiter, Taming Barrel and Tilt Distortion, Vector, 20 1 (2003) 87-95.
We consider J algorithms for removing barrel distortion from images using a spheical model for the distortion. Other algorithms are used for removing tilt distortion. These, and some more commonly needed operations, are put into an interactive form that uses control points to accomplish the transformations.
