Optimal correlation at low photon levels: study for astronomical images

Not Accessible

Your library or personal account may give you access

Abstract

We consider the problem of determining the unknown translation between two images. We analyze the performance of the optimal technique in presence of Poisson noise in comparison with the classical linear intercorrelation method, and we apply this approach to astronomical images.
