We present a filtering technique for extracting nuclei trajectories in 4D microscopy images of zebrafish embryogenesis based on a spatio-temporal granulometric analysis. Previous work showed that the morphological reconstruction operator with 4D structuring elements (SEs) allows us to directly recover nuclei trajectories as tubular-like structures in 4D. The performance and usability of this method is determined by two main factors. The first factor is the "intra-trajectory distance" -Dintra-, this means the maximum displacement of a nucleus between time frames, which is a function of the time step between image acquisitions, the spatial resolution and the cell speed. The other factor is the "inter-trajectory distance" -Dinter-, standing for the minimum distance between a nucleus and its neighbors in the spatio-temporal domain and is function of the microscopy resolution and the observed biological phenomena. | |
