Claim One:
1. A method for tracking at least one subject in a camera network, the method comprising the steps of: receiving, at a user interface, a selection of at least one subject in a first image taken by a first camera from a user; extracting, by a feature extraction module, one or more features of the at least one selected subject; sending, by the feature extraction module, the extracted one or more features of the at least one selected subject to one or more databases; initiating, by a ranking module, one or more search queries to a set of cameras within a camera network near the first camera, wherein the one or more search queries are used to determine, in an iterative manner, whether at least one of the extracted one or more features of the at least one selected subject is present in at least one image from at least one camera of the set of cameras; responsive to determining at least one of the one or more features are present in at least one image from at least one of the set of cameras, analyzing, by the ranking module, a set of results received from the one or more search queries to determine whether the at least one selected subject in the first image is present in one or more images from the set of cameras; responsive to determining the at least one selected subject is present in one or more images from the set of cameras, propagating, by one or more processors, a search of the at least one selected subject within the set of cameras within the camera network; utilizing, by the data retrieval and ranking module, a set of one or more search results to enhance camera-to-camera correlation; comparing, by the data retrieval and ranking module, an occurrence of a subject in the first camera with a plurality of images in a second camera; receiving, by a correlation refinement module, a refined feature-based correlation model to be used as a new input for further one or more search queries; and repeating, by the data retrieval and ranking module, one or more search queries with the new input in order to enhance the camera-to-camera correlation.
