This paper proposes a computational technique for extracting object cross-sectional shape information from digitized in-line Fresnel holograms that does not require prior knowledge of object depths but recovers relative depth information along the way. It is applicable to hologram segments involving a single object only. It is based on estimating Fourier transform magnitude and phase of the object from those of the hologram segment. The proposed technique is illustrated on a synthesized hologram.
