  abstract = {Complete and accurate video tracking is very difficult to achieve
	in practice due to long occlusions, traffic clutter, shadows and
	appearance changes. In this paper, we study the feasibility of event
	recognition when object tracks are fragmented. By changing the lock
	score threshold controlling track termination, different levels of
	track fragmentation are generated. The effect on event recognition
	is revealed by examining the event model match score as a function
	of lock score threshold. Using a Dynamic Bayesian Network to model
	events, it is shown that event recognition actually improves with
	greater track fragmentation, assuming fragmented tracks for the same
	object are linked together. The improvement continues up to a point
	when it is more likely to be offset by other errors such as those
	caused by frequent object reinitialization. The study is conducted
	on busy scenes of airplane servicing activities where long tracking
	gaps occur intermittently.},
