Abstract: The median root prior (MRP) iterative reconstruction algorithm favors locally monotonic images. MRP preserves sharp edges while reducing noise at the same time. Quantitative properties of MRP are good, because a sufficiently high number of iterations can be run. In order to make the visual quality of MRP images more conventional, the standard median was replaced by other order statistic operations, the Land FMH-filters. They allow for smoother appearance as they apply linear weighting together... (Update)
