Title: Digital video microscopy using deep learning

Particle tracking is essential in various fields of science, from study of cells in biology to studying particle dynamics in physics. The standard classical methods are algorithmic in nature, requiring heavy manual work to tweak the parameter to various conditions and tasks. In this project, we try to apply four such methods to different particle tracking tasks and show that these are better alternatives to standard methods. We use Deeptrack as the base framework for all our tasks. We show that CNN can track a single Janus particle suspended in a liquid and outperforms a standard method called radial center method especially under noisy and unsymmetrical particle conditions. We then demonstrate how the LodeSTAR algorithm outperforms the YOLO algorithm in tracking the centers of multiple particles in an image. Subsequently, we apply a method called MAGIK (Motion Analysis through GNN Inductive Knowledge) to predict the trajectories of the particles in a video.
