Image restoration for a class of linear spatially-variant degradations [link]Paper  doi  abstract   bibtex   
The Mellin transform is introduced as a technique for restoring images degraded by a class of spatially-variant degradations. This class includes the coma aberration and tilt in a cylindrical lens system. A technique for computing the Mellin transform via the fast Fourier transform is presented as well as examples of restorations by the use of the computer for the tilt degradation.
