• Abstract summary: We describe an automated analysis method to quantify the detailed growth dynamics of a population of bacilliform bacteria. We propose an innovative approach to frame-sequence tracking of deformable-cell motion by the automated minimization of a new, specific cost functional. We validate this automatic cell tracking algorithm using recordings of simulated cell colonies that closely mimic the growth dynamics of emphE. coli in microfluidic traps.

• Abstract: We describe an automated analysis method to quantify the detailed growth dynamics of a population of bacilliform bacteria. We propose an innovative approach to frame-sequence tracking of deformable-cell motion by the automated minimization of a new, specific cost functional. This minimization is implemented by dedicated Boltzmann machines (stochastic recurrent neural networks). Automated detection of cell divisions is handled similarly by successive minimizations of two cost functions, alternating the identification of children pairs and parent identification. We validate this automatic cell tracking algorithm using recordings of simulated cell colonies that closely mimic the growth dynamics of \emph{E. coli} in microfluidic traps. On a batch of 1100 image frames, cell registration accuracies per frame ranged from 94.5\% to 100\%, with a high average. Our initial tests using experimental image sequences of \emph{E. coli} colonies also yield convincing results, with a registration accuracy ranging from 90\% to 100\%.

  This paper proposes the novel end-to-end CAP framework to achieve efficient and stable cell tracking in one stage. CAP abandons detection or segmentation stages and simplifies the process by exploiting the correlation among the trajectories of cell points to track cells jointly. Cap demonstrates strong cell tracking performance while also being 10 to 55 times more efficient than existing methods.
