Abstract

Centroid determination is a relevant task for many optical measurement devices which is very often calculated over thresholded data. In presence of additive gaussian noise for the intensity, the influence of thresholding in the statistical properties of the calculated centroids is described. It has been performed theoretical, simulated and experimental analysis of the purposed influence model obtaining good agreement between them.
