1. A computerized method for assigning observations comprising:

  • receiving a plurality of first observations indicative of respective physical positions observed by a first sensor system and receiving a plurality of second observations indicative of respective physical positions observed by a second sensor system;

    assigning, by a computer, a set of pairs of the first and second observations predicted to correspond to the same physical position, the assigning comprising;

    receiving a cost function that specifies a cost for each assigned pair, the cost not independent of the assignment of any other assigned pairs in the set of assigned pairs; and

    determining the set of assigned pairs corresponding to an optimal value for the cost function by calculating, by the computer, a corresponding optimal value for a directed graph representative of possible assignments of first and second observations.
