Abstract
The use of a priori knowledge in restoring images reconstructed using limited data has been investigated by various authors [1-4] In these methods an attempt has been made to fill the missing spatial frequency information in the reconstructed image. The use of an. optical feedback system [2] and the use of a Fourier expansion minimization method [5] have been suggested to recover the lost information. The main disadvantge of these techniques is that they are very time consuming.
