1. A method comprising:
receiving one or more images generated by an image capture device that is configured to be relocated;
determining an estimated location of the image capture device based on (i) location data associated with the one or more images and (ii) metadata including historical location data associated with the image capture device, wherein determining the estimated location of the image capture device comprises combining, with a filter, (i) the location data associated with the one or more images and (ii) the metadata;
identifying, based upon a representation of a respective image of the one or more images and respective representations of a plurality of reference images, one or more reference images that are associated with the estimated location;
identifying an object of interest within the respective image generated by the image capture device based upon respective digital signatures of one or more objects of interest and at least some context associated with the one or more objects of interest that are depicted by the one or more reference images that have been identified, wherein each digital signature is representative of both the object of interest and at least some context associated with the object of interest; and
determining a defined location of the object of interest within the respective image based upon locations associated with the one or more objects of interest that are depicted by the one or more reference images that have been identified.
