1. A camera system, comprising: an object detection module operable to receive image data produced by at least one image capturing device, the image data representing multiple images of a field of view of the at least one image capturing device, and the object detection module operable to detect objects appearing in one or more of the multiple images; an object tracking module connected to the object detection module and operable to temporally associate instances of objects detected by the object detection module, wherein each detected object has a signature representing features of the detected object from the multiple images; and a match classifier connected to the object tracking module and operable to match object instances by analyzing data derived from the signature of each detected object based on matching parameters and non-matching parameters to indicate if two or more of the detected objects correspond to a same physical object.
