Abstract
A theoretical bound on the improvement possible due to knowledge of signal points, for the case of a Gaussian signal in Gaussian noise, has been calculated. Wiener and projections-onto-convex-sets restorations have been computed both with and without knowledge of the known points. The estimation errors are compared for different noise levels and blurs, and different numbers of known points
