Abstract :
A hybrid technique for restoration of both the Fourier Magnitude spectrum and Fourier Phase spectrum of image degraded by linear systems with additive noise is presented. Combined Fourier Magnitude spectrum - Fourier Phase spectrum is effected by cascading a statistical restoration filter with a modified Gerchberg-Saxton reconstruction algorithm.
