  abstract = {We present a novel method for jointly performing recognition of complex
	events and linking fragmented tracks into coherent, long-duration
	tracks. Many event recognition methods require highly accurate tracking,
	and may fail when tracks corresponding to event actors are fragmented
	or partially missing. However, these conditions occur frequently
	from occlusions, traffic and tracking errors. Recently, methods have
	been proposed for linking track fragments from multiple objects under
	these difficult conditions. Here, we develop a method for solving
	these two problems jointly. A hypothesized event model, represented
	as a Dynamic Bayes Net, supplies data-driven constraints on the likelihood
	of proposed track fragment matches. These event-guided constraints
	are combined with appearance and kinematic constraints used in the
	previous track linking formulation. The result is the most likely
	track linking solution given the event model, and the highest event
	score given all of the track fragments. The event model with the
	highest score is determined to have occurred, if the score exceeds
	a threshold. Results demonstrated on a busy scene of airplane servicing
	activities, where many non-event movers and long fragmented tracks
	are present, show the promise of the approach to solving the joint
	problem.},
