Abstract

In this paper the prior law introduced by Djafari [2] is compared to the prior law proposed by Gull [5] for the image reconstruction from projections. Furthermore, an approximation is proposed to simplify the calculation of the prior law introduced by Gull, in the case of data obtained from projections.
