Interactive system for recognition analysis of multiple streams of video
First Claim
1. A method of determining a best match between a target profile and a set of stored profiles, wherein a profile contains a set of identifying information extracted from an image set associated with the profile, the method comprising computer-implemented steps of:
- generating a plurality of confidence scores based on comparisons between the target profile and the set of stored profiles;
weighting the generated confidence scores using information external to the confidence scores; and
selecting a stored profile as the best match for the target profile based on the plurality of weighted confidence scores.

Abstract
A method of identifying an object captured in a video image in a multi-camera video surveillance system is disclosed. Sets of identifying information are stored in profiles, each profile being associated with one object. The disclosed method of identifying an object includes comparing identifying information extracted from images captured by the video surveillance system to one or more stored profiles. A confidence score is calculated for each comparison and used to determine a best match between the extracted set of identifying information and an object. In one embodiment, the method is used as part of a facial recognition system incorporated into a video surveillance system.

9. A method for maintaining associations between profiles and objects in an object recognition system, wherein a profile comprises a set of identifying information extracted from an image set associated with the profile, comprising the computer-implemented steps of:
-
automatically creating a first association between a first stored profile and a first object;
automatically creating a second association between a second stored profile and the first object;
providing a view of the image sets associated with the first and second stored profiles to a user;
receiving feedback from the user about the second association; and
modifying the second association in accordance with the received feedback. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 36)

19. A method of determining a best matching object for a target profile in an object recognition system in which each object recognized by the system is associated with a plurality of stored profiles, wherein a profile contains a set of identifying information extracted from an image set associated with the profile, the method comprising the computer-implemented steps of:
-
generating a plurality of confidence scores based on comparisons between the target profile and a set of stored profiles;
determining an object associated with each generated confidence score;
analyzing the generated confidence scores and determined associated objects; and
selecting a best matching object in accordance with the analyzed confidence scores and determined associated objects. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 37)
