4. The computer readable storage medium of claim 3 , wherein the first time interval and the second time interval are shortened using minimum status interval duration statistics and minimum status transition time statistics that are determined from the comparison of a target status history value of the known location of the candidate target at a time value just before a time value of the sensor data and an inferred target status value of the sensor data and a target status history value of the known location of the candidate target at a time value just after a time value of the sensor data and the inferred target status value of the sensor data.

The computer readable storage medium of claim 4 , wherein the inferred target status value is inferred from the input sensor data using a target class of the candidate target, a geographic region wherein the candidate target is located, and statistical analysis of status histories of candidate targets in the same target class as the candidate target.
