The restoration of old movies using the newly developed rational functions filters is considered. After localization of the stationary and random defects, a spatial rational interpolator scheme is proposed to reconstruct the missing data. The experimental results demonstrate the usefulness of the rational interpolator in an application involving the restoration of defects in old movies. The resulting edges obtained using the proposed interpolator are free from blockiness and jaggedness.
