We present an analysis of the recognition performance of 3-D objects reconstructed
from digital holograms recorded under photon counting conditions. The digital
holograms are computed by applying four-step phase-shifting techniques to interferograms
recorded with weak coherent light. Recognition capability is analyzed as a function of the
total number of photons by using a maximum-likelihood approach adapted to one-class
classification problems. The likelihood is modeled assuming a Gaussian distribution, whose
centroid corresponds to the highest value in a mixture of two Gaussian values. The recognition
capability is studied both in terms of the axial distance and the lateral position of the
reconstructed 3-D object. [-]
