摘要： A determination method implemented by a computer, the determination method including: in response to acquiring a primary image captured by a camera, calculating, based on a size of a region of the subject, an estimated value of a distance to a subject that is specified and included in the primary image; acquiring a secondary image captured by the camera focused on a position according to the calculated estimated value; and determining, based on the acquired secondary image, whether the subject is a display object.

摘要： To improve authentication accuracy. A processing unit (12) receives a plurality of pieces of captured data of a person, and generates weight information indicating a weight applied to each of the plurality of pieces of captured data on the basis of quality of each of the plurality of pieces of captured data and the number of the plurality of pieces of captured data. When representative data representing the plurality of pieces of captured data is calculated from the plurality of pieces of captured data, the processing unit (12) applies an algorithm in which the smaller the weight indicated by the generated weight information, the smaller an influence of each of the plurality of pieces of captured data on a calculation result of the representative data.

摘要： A computational cost of determination is reduced.
An information processing apparatus (10) calculates a parameter for each of a plurality of layers included in a neural network (13) through machine learning using a plurality of image datasets each containing a human biometric image. The information processing apparatus (10) generates a determination model of determining the authenticity of a human biometric image included in a received image dataset, by setting a parameter (18) calculated for a layer (15) of the neural network (13) in the layer (15) included in a neural network (14) that includes the layer (15) and does not include a layer (16).

摘要： In an authentication method, a computer executes a process including: obtaining a captured image captured by a camera; selecting one facial image from a plurality of facial images based on a position of each of the plurality of facial images included in the obtained captured image in the captured image; referring to a storage unit that stores pieces of biometric information associated with the respective plurality of facial images and specifying a piece of the biometric information associated with a facial image in which a degree of similarity to the selected facial image satisfies a criterion; and performing, when biometric information detected by a sensor is received, authentication based on verification of the specified piece of the biometric information against the received biometric information.

摘要： A similarity calculation device (200) refers to a storage unit that stores each binarized first code corresponding to a plurality of first media data. The similarity calculation device (200) calculates each similarity between a second media data and each of the first media data based on a probability that a second code obtained by binarizing a feature vector corresponding to the second media data is converted into the first code.

摘要： It is characterized by including an image acquisition unit 41 that acquires an image 53 that includes a face of one or more persons, an extraction unit 42 that specifies a region that a face of a head person 12a of a waiting line in which the one or more persons line up appears from the acquired image 53 and extracts feature 14 of the face of the head person included in the specified region, a selection unit 43 that, by collating the extracted feature 14 with feature 14 stored in a storage unit 5 that stores the feature 14 that indicates facial characteristics of a plurality of persons 12 and biometric information 13 of each of the persons 12, selects a group G of persons similar to the head person 12a among the plurality of persons 12, a biometric information acquisition unit 51 that acquires the biometric information 13 of the head person 12a, and an authentication unit 52 that authenticates the head person 12a by collating the biometric information 13 of each person included in the group G among the biometric information 13 stored in the storage unit 5 with the acquired biometric information 13 of the head person 12a.
