Abstract
A face image processing apparatus, includes: a face region detecting unit configured to detect a face feature point of a person from a plurality of images picked up by a plurality of imaging units respectively, to detect a face region; a face feature extracting unit configured to extract a face feature from an image of the face region detected by the face region detecting unit; a person recognizing unit configured to calculate a similarity measure based on a face feature of a specific person being previously registered and the face feature extracted by the face feature extracting unit to recognize the person; and an output apparatus which outputs a recognition result in the person recognizing unit.
Claims4
A face image processing apparatus, comprising:
- a face region detecting unit including a plurality of face region detecting sections each configured to detect a face feature point of a person to be identified from one of a plurality of images picked up by a plurality of imaging units, respectively, to detect a face region;
- a face feature extracting unit including a plurality of face feature extracting sections each configured to extract a face feature from one of the images corresponding to the face region detected by one of the plurality of face region detecting sections;
- a photograph judging unit configured to compare a first face feature extracted by a first one of the plurality of face feature extracting sections with a second face feature extracted by a second one of the plurality of face feature extracting sections to judge whether a photographic subject imaged by the plurality of imaging units is a photograph;
- a person recognizing unit configured to calculate a similarity measure based on a face feature of a specific person being previously registered and a face feature determined from the face features extracted by the face feature extracting sections, to recognize the person to be identified;
- and
- an output apparatus providing a recognition result received from the person recognizing unit.
A certification apparatus, comprising:
- a plurality of imaging units which pick up a plurality of images of a first person, respectively;
- a plurality of face region detecting units each configured to detect a face feature point of the first person from each of the plurality of images to detect a face region corresponding to the face feature point;
- a face feature extracting unit configured to extract a face feature from images each corresponding to the face region detected by one of the plurality of face region detecting units;
- a photograph judging unit configured to judge whether a photographic subject imaged by the plurality of imaging units is a photograph;
- and
- a person recognizing unit configured to calculate a similarity measure between a face feature of a specific person being previously registered and the face feature extracted by the face feature extracting unit, to recognize the first person;
- wherein the face feature extracted by the face feature extracting unit includes a plurality of face features corresponding to the respective images;
- and
- the photograph judging unit compares the plurality of face features with each other to judge whether the photographic subject is a photograph.
A certification apparatus, comprising:
- a plurality of imaging units which pick up a plurality of images respectively;
- a plurality of face feature point extracting units each configured to extract a face feature point from one of the plurality of images;
- an others mixture judging unit configured to judge whether an identical person is indicated by a first face feature point extracted by a first one of the plurality of face feature point extracting units and a second face feature point extracted by a second one of the plurality of face feature point extracting units;
- and
- a person recognizing unit configured to recognize a person according to the first and second face feature points when the others mixture judging unit judges that the identical person is indicated.
