Ts. Zaccheo et al., ESTIMATING THE CRAMER-RAO BOUND FOR ASTRONOMICAL OBSERVATIONS - APPLICATION TO THE RICHARDSON-LUCY ALGORITHM, The Astrophysical journal, 458(2), 1996, pp. 742
This work addresses the problem of assigning confidence intervals to r
estored data obtained by applying the Richardson-Lucy algorithm to ast
ronomical observations. The proposed solution is to estimate the Crame
r-Rao bound, which describes the minimum obtainable mean square error
associated with a given estimate of a parameter. This paper presents a
compact method for describing the bound for Richardson-Lucy estimates
. It was developed based on previously described bounds for linear res
toration techniques such as Wiener filter estimates. Both one- and two
-dimensional examples are presented.
