Abstract
Image restoration and enhancement are ones of fundamental problems in image processing. Many research activities, therefore, have been continuously carried out during almost three decades [1, 2, 3]. Inverse filtering, Wiener filtering with or without constrains, and Kalman filtering-smoothing techniques have been applied to the image restoration problem in the cases of either known or unknown blurring functions. Many methods in image restoration and enhancement rely upon the Fourier transformation and its discrete version; DFT (discrete Fourier transformation).
