A candidate face image and attribute information of each imaging attribute item are acquired. For each imaging attribute item, attribute information is extracted from a database that stores attribute information that has a degree of participation in false authentication greater than a participation degree threshold, among attribute information of analyzed imaging attribute items of analyzed master face images that resulted in false authentication in face image authentication. For each imaging attribute item, whether or not the extracted attribute information has a similarity to the acquired attribute information of the each imaging attribute item greater than a similarity threshold is determined. For each imaging attribute item for which the similarity is greater than the similarity threshold, a weight is assigned. A total score is calculated by summing the weights. When the total score satisfies a predetermined threshold value, the candidate face image is determined as inappropriate as a master face image.

Master face image registration apparatus, registration method, program, and recording medium

A face authentication apparatus includes: an acquisition unit that acquires face image data of a person from image capturing apparatuses, a determination unit that determines whether registration data, having degree of matching with the face image data that is equal to or more than a threshold value, is registered in a storage device, a prompting unit that prompts the person to input identifying information when the determination unit determines that the registration data is not registered in the storage device, a reception unit that receives the identifying information input, a registration after input reception unit that registers the face image data as registration data in the storage device when the reception unit successfully receives an input of the identifying information, and a setting unit that sets a threshold value, to be used by the determination unit, in association with the registration data registered by the registration after input reception unit.

Face authentication apparatus, face authentication method, and computer-readable recording medium

An apparatus for face image candidate determination for authentication, including a storage and at least one processor wherein the storage stores a reference face image in association with an attribute of the image for each registered person and a score threshold value for each combination of attributes of face images to be collated. The processor configured to: acquire a face image of a person to be determined as a face image for determination, determine an attribute of the face image, collate the reference face image with the face image and calculates a score indicating a degree of matching, and select a reference face image satisfying the score threshold value as a face image candidate for authentication and selects the face image candidate and the score thereof as authentication information of the face image for determination.

The present invention provides a new stock control system that can grasp the stock status of objects to be controlled and is excellent in convenience. The stock control system of the present invention includes a shelf; a marker; an image acquisition unit; a storage unit; an analysis unit; and an alert unit. The shelfis a shelf on which an object to be controlledis placed. The markeris disposed in the shelfat a position where it is shielded from the image acquisition unitdue to the placed object to be controlled. The image acquisition unitacquires an image of the marker. The storage unit updates and stores on-time stock information of the object to be controlledplaced on the shelfbased on sales information of the object to be controlled. The analysis unit analyzes, upon acquisition of the image of the markerby the image acquisition unit, the on-time stock information in the storage unit. The alert unit outputs an alert according to an analysis result of the analysis unit.
