Title: Tracking via Classification Abstract: The talk will be focused on classifiers fusion for target tracking. More in detail, an ensemble of classifiers can be exploited to build on-the-fly a model to represent the appearance of an object. The combination of experts can be constantly updated, to learn variations in the appearance of the target through the frames providing a means for detection and tracking. The problem of how multiple classifiers can be fused together, that is the choice of the rule to merge their outputs to reach a final consensus, will be discussed. Three criteria to improve the performance of a classifier ensemble will be proposed; to test them, the classification problem as a means to get a better target tracking performance on real-world multimedia video sequences will be examined.
