Optimal correlation at low photon levels: study for astronomical images.

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.
