Abstract (in Japanese) (See Japanese page) 
(in English) We derive a deterministic algorithm that restores and segments an image using belief propagation and a variational Bayesian method based on regionbased latent variables and a coupled MRF model. This algorithm estimates two hyperparameters as well as infers the original image andthe latent variables. In addition, the algorithm carries out model selection by minimizing the variational free energy. Through experiments using an artificial image and a natural image degraded by Gaussian noises, we show that the derived algorithm has the potential ability to restoreand segment using a single noisy image.
