A Discrete Chain Graph Model for 3d+t Cell Tracking with High Misdetection Robustness

Abstract

Tracking by assignment is well suited for tracking a varying number of divisible cells, but suffers from false positive detections. We reformulate tracking by assignment as a chain graph–a mixed directed- undirected probabilistic graphical model–and obtain a tracking simulta- neously over all time steps from the maximum a-posteriori configuration. The model is evaluated on two challenging four-dimensional data sets from developmental biology. Compared to previous work, we obtain improved tracks due to an increased robustness against false positive detections and the incorporation of temporal domain knowledge.
