• We investigate a restoration process for a gray-scale pattern given by a snapshot of the Q-states ferromagnetic Husimi–Temperly model within a framework of a Bayesian inference. By using a generating function of path-integral representation, we derive an equation which describes the restoration process for the gray-scale pattern. We investigate two systems: system 1 in which the gray-scale value takes on {−1,−1+2/(Q−1),···,1−2/(Q−1),1} and system 2 in which the gray-scale value takes on {1,···,Q}. We find that there exists difference between Q=2 and Q≥3 as for behavior of the restoration process for the system 1.
