IDENTIFICATION DEVICE, IDENTIFICATION METHOD, AND STORAGE MEDIUM
First Claim
1. An identification device that performs identification according to a face area contained in image data, comprising:
- a feature data extraction unit configured to extract feature data from a face area in each of a plurality of frames of image data, as extracted feature data;
a storage unit configured to register therein feature data for use in the identification;
an identification unit configured to perform identification through comparison between the feature data registered in said storage unit and the extracted feature data;
a tracking unit configured to identify an identical face area in consecutive ones of the frames; and
a registration unit configured to be operable when said identification unit identifies a face area in a first frame as one of the frames, but said identification unit does not identify a face area in a second frame following the first frame, which is identified by said tracking unit as identical to the identified face area in the first frame, to register the extracted feature data associated with the face area in the second frame, as additional feature data, in said storage unit.

Abstract
An identification device capable of improving identification accuracy. The identification device performs identification according to a face area contained in image data. Feature data is extracted from a face area in each of frames of image data. The extracted feature data is registered in a person database section. Identification is performed through comparison between the feature data registered in the person database section and the extracted feature data. A tracking section identifies an identical face area in consecutive frames. If a face area is identified in a first frame, but a face area in a second frame following the first frame, which is identified by the tracking section as identical to the identified face area in the first frame, is not identified, the extracted feature data associated with the face area in the second frame is registered as additional feature data in the person database section.

13. An identification method used by an identification device that performs identification according to a face area contained in image data and is provided with a storage unit in which feature data associated with a face area for use in the identification is registered as registered feature data, comprising:
-
extracting feature data from a face area in each of a plurality of frames of image data, as extracted feature data; performing identification through comparison between the feature data registered in the storage unit and the extracted feature data; identifying an identical face area in consecutive ones of the frames; and registering, when a face area in a first frame as one of the frames is identified, but a face area in a second frame following the first frame, which is identified as identical to the identified face area in the first frame, is not identified, the extracted feature data associated with the face area in the second frame, as additional feature data, in the storage unit. - View Dependent Claims (14)

15. A non-transitory computer-readable storage medium storing a computer-executable program for causing a computer to execute an identification method used by an identification device that performs identification according to a face area contained in image data and is provided with a storage unit in which feature data associated with a face area for use in the identification is registered as registered feature data,
wherein the identification method comprises: -
extracting feature data from a face area in each of a plurality of frames of image data, as extracted feature data; performing identification through comparison between the feature data registered in the storage unit and the extracted feature data; identifying an identical face area in consecutive ones of the frames; and registering, when a face area in a first frame as one of the frames is identified but a face area in a second frame following the first frame, which is identified as identical to the identified face area in the first frame, is not identified, the extracted feature data associated with the face area in the second frame, as additional feature data, in the storage unit. - View Dependent Claims (16)
