Claim:
1. A method, comprising: receiving first detection information for a plurality of objects, the first detection information relating to a first characteristic of the objects; receiving second detection information for the objects, the second detection information relating to a second characteristic of the objects; determining first detections based upon the first detection information and second detections based upon the second detection information; formulating a first trellis graph for the first detections and a second trellis graph for the second detections, the first and second trellis graphs including corresponding first and second nodes at a plurality of time frames; and determining a tracking of a selected one of the objects based upon a simultaneous shortest path for the selected object through both the first and second trellis graphs based upon a first path through the first trellis graph, a second path through the second trellis graph, and sidekick information between a selected node of one of the first and second trellis graphs at a selected time frame with at least one node of the other one of the first and second trellis graphs at a previous time frame.
