1. A method for making a correspondence between a face camera track and a behavior camera track, comprising the following steps of: a) constructing a database of pairwise person images, where each pairwise person image comprises a person image from a face camera and a person image from a behavior camera, b) annotating the database of pairwise person images based on whether the pair of person images in each pairwise person image belongs to the same person, c) training at least a pairwise person verification machine to estimate appearance match scores between the pair of person images in the pairwise person images from the database, d) acquiring a person image from the face camera track and a person image from the behavior camera track to form a second pairwise person image, and e) estimating an appearance match score between the pair of person images in the second pairwise person image, using the pairwise person verification machines on the second pairwise person image to calculate correspondence between the face camera track and the behavior camera track.
