2D Particle Filter Realization in MRF Modelled Images

Abstract

In this study, we present a 2D particle filter realization on images modelled by MRFs. The essential feature of the approach is the discretization of the posterior density and the evaluation of the MSE estimates of the image using the discretized posterior. The calculation is completely numerical rather than analytical. For simplicity, we adapted a linear image formation model and we studied the noise filtering problem.
