To participate in the MCT challenge, the participant is required to conduct at least one experiment. But if you want to put the tracking results in the ranking, all the three experiments must be conducted. To give an overall ranking, an average of the tracking accuracies of the three experiments is calculated according to Formula (1) to give the ranking for each subset in the NLPR_MCT dataset first. And then participants' final positions in the ranking are determined by integrating the ranking results on all the subsets according to Formula (2). For a single experiment on a subset, the performance of the trackers is evaluated by a Multi-Camera Tracking Accuracy (MCTA) according to Formula (3). In all the experiments, the MCT challenge uses the same evaluation criterion.

The MCT challenge provides an evaluation kit. Participants can use it to evaluate their algorithms (available for Matlab and C algorithms). The evaluation kit can be downloaded below:
The algorithms submitted have to be integrated and run with the MCT challenge evaluation kit, which will automatically perform the chosen experiment by the evaluation criterion on the NLPR_MCT dataset.
