Teetool -- a probabilistic trajectory analysis tool

Teetool is a Python package which models and visualises motion patterns found in two- and three-dimensional trajectory data. It models the trajectories as a Gaussian process and uses the mean and covariance of the trajectory data to produce a confidence region, an area (or volume) through which a given percentage of trajectories travel.
The confidence region is useful in obtaining an understanding of, or quantifying, dispersion in trajectory data. Furthermore, by modelling the trajectories as a Gaussian process, missing data can be recovered and noisy measurements can be corrected.
Teetool is available as a Python package on GitHub. The project includes Jupyter Notebooks, showing examples for two- and three-dimensional trajectory data.
