The MOT Metrics module is designed to evaluate multi-object tracking (MOT)

aiding in the iterative improvement of tracking algorithms."""

Calculates how good are predictions given some references, using certain scores

predictions: list of predictions to score. Each predictions

reference should be a string with tokens separated by spaces.

If specified, this is the minimum Intersection over Union (IoU) threshold to consider a detection as a true positive.
Default is 0.5.
