Different layers in CNNs provide not only different levels of abstraction for describing the objects in the input but also encode various implicit information about them.

Employing one or more additional classifiers to break the self-learning loop in tracing-by-detection has gained considerable attention.

We introduced the idea of most informative sampling, in which the sampler attempts to select samples that trouble the classifier of a discriminative tracker.

To remove this redundancy and have an effective ensemble learning, it is critical for the committee to include consistent hypotheses that differ from one-another, covering the version space with minimum overlaps.

However, by updating all of the ensemble using a shared set of samples and their final labels, such diversity is lost or reduced to the diversity provided by the underlying features or internal classifiers' dynamics.

To cope with variations of the target shape and appearance, the classifier is updated online with different samples of the target and the background.

We also introduce a budgeting mechanism which prevents the unbounded growth in the number of examples in the first detector to maintain its rapid response.
