| Abstract(in English) | In this paper, we treat a restoration problem for noisy-degraded image based on the Bayesian inference. As long as we know, it is usually assumed that superimposed noise has no correlation among the pixels. We discuss spatially correlated noise in this paper. The generative statistical models for the original image and the noise are assumed to obey multi-dimensional Gaussian distributions, whose covariance matrixes have translational invariance. We can derive exact description for expectation of the restored image using the Fourier transformation, and found that resultant values of hyper-parameter estimations for minimum error and maximal posterior marginal criteria coincide with each other where generative probabilistic model and that of restoration process belong to the same class, while they do not for the different classes. |
