Abstract

Pictures that are to be transmitted through a distorting imaging system may be deliberately modified to compensate for that distortion. We investigate the applicability of inverse-filtering techniques to this pre-compensation problem and use examples to demonstrate the nature of the necessary picture modification. Potential improvement of two-line resolution is also discussed.
