1. A method for re-identifying a query object moving from a first camera view to a second camera view, the method comprising the steps of: accessing a first set of image frames captured from the first camera view and a second set of image frames captured from the second camera view, each frame in the first set of image frames including an instance of the query object and each frame in the second set of image frames including an instance of a candidate object; selecting a first representative frame from the first set of image frames and a second representative frame from the second set of image frames based on a plurality of intra-camera object appearance distances between frame pairs in each set of image frames; and re-identifying the candidate object in the second camera view as the query object in the first camera view based on at least one inter-camera object appearance distance calculated between the first representative frame and the second representative frame.
