Abstract

Super-Resolution (SR) image reconstruction can be viewed as a three tasks process: registration or motion estimation, Point Spread Function (PSF) estimation and high resolution (HR) image reconstruction. In this paper, we propose a new method based on the Bayesian estimation with a Gauss-Markov-Potts prior model (MGMPP) where the main objective is to get a new High Resolution (HR) image from a set of severely blurred, noisy, rotated and shifted Low Resolution (LR) images. As a byproduct of our prior model, we obtain jointly a SR image and an optimal segmentation of it. The proposed algorithm is unsupervised. A comparison of the performances of the proposed method with some classical and recent SR methods are provided in simulation. The simulation results show that Bayesian estimation with a MGMPP algorithm, outperforms methods proposed by Marcel and al, Lucchese and Cortelazzo, Vanderwalle, and Keren.
