HUMAN FACE RECOGNITION AND USER INTERFACE SYSTEM FOR DIGITAL CAMERA AND VIDEO CAMERA
First Claim
1. A face recognition method, comprising:
- providing an image;
defining a target face from said image, said target face having a set of extracted target facial features;
generating a candidate list of one or more candidate faces for said target face, each candidate face on said candidate list having a set of candidate facial features thereof;
determining a matching candidate face out of said candidate list based on comparing said target facial features with said candidate facial features; and
updating the candidate facial features of said matching candidate face with said target facial features.

Abstract
The present invention discloses a face recognition system which includes a face recognition method and associate apparatus. The disclosed method provides improved face matching accuracy by introduction of user intervention. When a target face to be recognized has been detected, a candidate list is generated and the user is allowed to actively select a matching candidate face out of the candidate list by entering a user input through a user interface provided by the disclosed apparatus. Data of the target face are then automatically registered to a database where the candidate face data are stored for updating the data of the matching candidate.

1. A face recognition method, comprising:
-
providing an image; defining a target face from said image, said target face having a set of extracted target facial features; generating a candidate list of one or more candidate faces for said target face, each candidate face on said candidate list having a set of candidate facial features thereof; determining a matching candidate face out of said candidate list based on comparing said target facial features with said candidate facial features; and updating the candidate facial features of said matching candidate face with said target facial features.

2. A face recognition method, comprising:
-
providing an image; defining a target face from said image, said target face having a set of extracted target facial features; generating a candidate list of one or more candidate faces, each candidate face having a set of candidate facial features thereof; comparing said target face with each said candidate face based on said target facial features and said candidate facial features to determine a first matching candidate face out of said candidate list; receiving user input, said user input designating a second matching candidate face out of said candidate list, wherein in response to said user input if said first and second matching candidates are identical, updating the candidate facial features of said first matching candidate face with said target facial features, otherwise updating the candidate facial features of said second matching candidate face with said target facial features. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11)

12. A face recognition apparatus, comprising
a display module for displaying an image; -
a detection module, electrically coupled with said display module, for detecting a target face from said image and whereupon to generate a detection result designating said target face, said target face having a set of extracted target facial features; a candidate list-generating module, electrically coupled with said detection module and a storage medium, for generating a candidate list of one or more candidate faces for matching said target face, each candidate face having a set of candidate facial features thereof, said candidate facial features data being stored in a database stored in said storage medium; a comparison module, electrically coupled with said candidate list-generating module and said storage medium, for comparing said target face with each said candidate face based on said target facial features and the candidate facial features of each said candidate face, whereupon to generate a first comparison result indicating a first matching candidate face out of said candidate list; and a database-updating module, electrically coupled with said detection module, said comparison module and said storage medium, receiving said target facial features data from said detection module and said first matching candidate data from said comparison module, for updating the candidate facial features of said first matching candidate face stored in said database with said target facial features. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)

22. An electronic image capturing device, comprising:
a display for presenting at least one window, wherein a first window displays an image; a second window displays one or more first face thumbnails, said first thumbnail being faces detected from said image, one of which a target face to be recognized; a third window displays one or more second face thumbnails, said second thumbnail being candidate faces in terms of matching said target face, one of said candidate faces being a user-selected candidate face; a fourth window displays one or more third face thumbnail, said third face thumbnail being faces or facial features associated with said user-selected candidate face; and a user input module, for receiving at least one user input, wherein a first user input designates said target face out of said first thumbnails; and a second user input designates said user-selected candidate face out of said second thumbnails. - View Dependent Claims (23, 24, 25)
