<p>Posterior mean image for unsmoothed data of the approach proposed in this paper is shown in the upper left corner. Results of SPM's frequentist and Bayesian implementation are shown in the second and third column for unsmoothed (upper row) and smoothed (lower row) data, respectively. The true parameter image is shown in the lower left corner. The approach proposed in this paper performs best as demonstrated by the MSE and by visual inspection.</p
