We derive a deterministic algorithm that restores and segments image using switching state-space model and variational Bayesian method. This algorithm estimates hyperparameters as well as infers the original image and the latent variables by Bayesian inference. In this algorithm, hyperparameters that control the smoothness of the original image estimate for each region. Through experiments using an artificial image and a natural image degraded by Gaussian noises, we show that the derived algorithm can restore and segment using a single noisy image. |
