Bayesian estimation theory has been widely used in the field of image processing. In this paper, the estimation technique by Bayesian Maximum A Posteriori (MAP) is investigated with respect to the issue of image denoising, and the formula of the Minimum Mean Squared Error (MMSE)-like estimation is derived. Based on the discussion, a method is proposed which can deduce Wiener filtering formula by using Posterior Mean criteria.
