u-track is a multiple-particle tracking software that is designed to:
- Track dense particle fields
- Close gaps in particle trajectories resulting from detection failure
- Capture particle merging and splitting events resulting from occlusion or genuine aggregation and dissociation events
Its core is based on formulating correspondence problems as linear assignment problems and searching for a globally optimal solution. The software is written in Matlab, and can be called either via a Graphical User Interface or command line.
