2. The method of claim 1 wherein the identifying includes computing a likelihood for each of the extended hypotheses, the likelihood being a function of connection probabilities each associated with a respective trajectory of that hypothesis, each connection probability being a measure of the probability that an object that terminates the associated trajectory is, in fact, an object in the area under surveillance that is on that trajectory.
