Weiner Filter
The inverse filtering approach presented earlier was "ad hoc" in the choise of . Wiener filtering is more objective and incorporates the characteristics of noise and the degradation function in the restoration process. Assumption: Image and noise are considered as random variables. Aim is to find an estimate ˆf(x, y) of the uncorrupted image f(x, y) such that the mean square error between the two is minimum.
