Query: Lightweight and Scalable Particle Tracking and Motion Clustering of 3D
  Cell Trajectories   Tracking cell particles in 3D microscopy videos is a challenging task but is
of great significance for modeling the motion of cells. Proper characterization
of the cell's shape, evolution, and their movement over time is crucial to
understanding and modeling the mechanobiology of cell migration in many
diseases. One in particular, toxoplasmosis is the disease caused by the
parasite Toxoplasma gondii. Roughly, one-third of the world's population tests
positive for T. gondii. Its virulence is linked to its lytic cycle, predicated
on its motility and ability to enter and exit nucleated cells; therefore,
studies elucidating its motility patterns are critical to the eventual
development of therapeutic strategies. Here, we present a computational
framework for fast and scalable detection, tracking, and identification of T.
gondii motion phenotypes in 3D videos, in a completely unsupervised fashion.
Our pipeline consists of several different modules including preprocessing,
sparsification, cell detection, cell tracking, trajectories extraction,
parametrization of the trajectories; and finally, a clustering step.
Additionally, we identified the computational bottlenecks, and developed a
lightweight and highly scalable pipeline through a combination of task
distribution and parallelism. Our results prove both the accuracy and
performance of our method.
