摘要：
In this work we analyze the effects of signal-dependent noise in the input scenes of optical correlators. We propose several algorithms to process this noise and we evaluate their performance. In particular we compare the strategy of restoring the input scene with noise and perform the correlation, with the alternative of correlating directly using filters designed to take into account the noise model in the input image.
