1. A system for estimating and tracking multiple attributes of multiple objects from multi-sensor data, the system comprising: a feature module operable to identify features associated with sensor data, the sensor data representing data captured by at least one of a plurality of sensors; an object detector operable to determine multiple probable objects based at least in part on the identified features, the determination being made in parallel for the identified features; a hypothesis generator operable to form hypotheses based at least in part on associating identified features with the multiple probable objects; a grouping module operable to attribute the formed hypotheses to channels; and a tracking module operable to construct sequences of the formed hypotheses; the tracking module being configured to provide the channels and constructed sequences.
