IMAGE PROCESSING DEVICE, METHOD, AND PROGRAM
PROBLEM TO BE SOLVED: To certainly perform face image authentication. SOLUTION: An extraction part 82 extracts a feature quantity from face image data of a face image of a person to be authenticated imaged by an imaging part 81 to supply them to an authentication part 86. The extraction part 84 extr...

| description | PROBLEM TO BE SOLVED: To certainly perform face image authentication. SOLUTION: An extraction part 82 extracts a feature quantity from face image data of a face image of a person to be authenticated imaged by an imaging part 81 to supply them to an authentication part 86. The extraction part 84 extracts a feature quantity from the face image data of the face image of the person to be authenticated previously imaged and stored in a face image memory 83 to supply them to an estimation part 85. The estimation part 85 obtains an estimated distribution range in which the feature quantity of the face image imaged by the imaging part 81 is estimated to distribute based on the feature quantity supplied from the extraction part 84, and supplies it to the authentication part 86. The authentication part 86 determines whether or not the feature quantity supplied from the extraction part 82 is the value within the estimated distribution range. The present invention may be applied to an image processing device performing the face image authentication. COPYRIGHT: (C)2007,JPO&INPIT |
