Broadcast identifier enhanced facial recognition of images

摘要

A system may recognize faces within an image by using wireless identifiers captured at the time the image was taken to determine a list of candidates for facial recognition. A database may contain people associated with one or more wireless identifiers, which may be identifiers associated with various protocols, such as Bluetooth, cellular telephones, WiFi, or other protocols. In some cases, the list of candidates may be expanded by using candidate's social networks. The recognized faces may be tagged in the image as metadata, then used in various scenarios. In one scenario, an album of images from an event may be created by matching people who were tagged in images. In another scenario, people may exchange business contact information or social network contacts by taking images of each other.

主权项

1. A system comprising:
a database comprising broadcast identifiers associated with people; and a facial recognition system operable on a processor that:
receives a first image comprising a first face said image being taken by a first user;receives a first broadcast identifier captured when said first image was taken;determines a first set of candidates for facial recognition from said database based on said first broadcast identifier;performs facial recognition on said first image to match said first image to one of said first set of candidates;receives a second image comprising a second face, said second image taken by a second user;receives a second broadcast identifier captured when said second image was taken;determines a second set of candidates for facial recognition from said database based on said second broadcast identifier; andperforms facial recognition on said second image to match said second image to one of said second set of candidates.
