Device and method for automatic participant identification in a recorded multimedia stream
First Claim
1. A device comprising:
- a receiver configured to receive a video conference format coded data stream;
a conversion unit configured to convert the video conference format coded data stream to a multimedia stream in a defined multimedia streaming format and store the multimedia stream and searchable metadata in a content database;
a user database including identities of known individuals stored with associated facial images; and
a face recognition unit configured to,detect a face in a video stream included in the multimedia stream,define subsets including facial images of one or more of the known individuals, where the subsets are ranked according to a probability that their respective one or more known individuals will appear in the video stream,compare the detected face to the subsets in consecutive order starting with a most probable subset, until a match is found, andstore an identity of the detected face as searchable metadata in the content database in response to the detected face matching a facial image in one of the subsets.

Abstract
The present disclosure discloses a method for identifying individuals in a multimedia stream originating from a video conferencing terminal or a Multipoint Control Unit, including executing a face detection process on the multimedia stream; defining subsets including facial images of one or more individuals, where the subsets are ranked according to a probability that their respective one or more individuals will appear in a video stream; comparing a detected face to the subsets in consecutive order starting with a most probable subset, until a match is found; and storing an identity of the detected face as searchable metadata in a content database in response to the detected face matching a facial image in one of the subsets.

12. A method for identifying individuals in a multimedia stream originating from a video conferencing terminal or a Multipoint Control Unit, the method comprising:
-
executing, at a device, a face detection process on the multimedia stream; defining, at the device, subsets including facial images of one or more individuals, where the subsets are ranked according to a probability that their respective one or more individuals will appear in a video stream; comparing, at the device, a detected face to the subsets in consecutive order starting with a most probable subset, until a match is found; and storing, at the device, an identity of the detected face as searchable metadata in a content database in response to the detected face matching a facial image in one of the subsets. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
