     2D FREQUENCY DOMAIN FILTERS

     These routines operate on images which are in the frequency
     domain.

     SHORT DESCRIPTION OF ROUTINES

     Low-Pass Filter -   Perform low-pass filtering on an image
                         in the frequency domain.

     High-Pass Filter -  Perform high-pass filtering on an image
                         in the frequency domain.

     Band-Pass Filter -  Perform band-pass filtering on an image
                         in the frequency domain.

     Band-Reject Filter -
                         Perform band-reject filtering on an
                         image in the frequency domain.

     Inverse Filter -    Perform image restoration by inverse
                         filtering in the frequency domain.

     Wiener Restoration -
                         Perform image restoration by Wiener
                         (least-squares) filtering.

     Space-varying Restoration -
                         Perform image restoration of space-
                         varying point spread functions.

     Bandlimited extrapolation -
                         Perform bandlimited extrapolation or
                         adaptive apodization
