Abstract(in English) | Super-resolution is a technique to estimate higher resolution image from multiple low-resolution observed images. We treat Bayesian image super-resolution with a compound Markov random field prior. In preceding studies, point estimation by marginal likelihood maximization was employed on either degradation transformation parameters or high-resolution image. When both the hyper-parameters and those parameters are estimated simultaneously, such point estimation may cause over fitting problem since the flexibility will increase. In this report, we try high accurate estimation avoiding over fitting by estimating all parameters in Bayesian inference using a approximate method combining Taylor expansion and Laplace method with variational Bayesian method. |
