Abstract

Using the estimate-maximize technique for maximum-likelihood estimation, a multiframe generalization of the Richardson- Lucy algorithm is derived which encompasses additive Poisson noise sources in addition to source dependant photon noise. This enables the estimation algorithm to properly treat situations in which the signal is similar in strength to noise sources such as background radiation and ark current. Simulations are used to investigate the level of restoration performance that may be expected at various noise source strengths.
